[Q] VZW m8 to stright-talk

Hey everyone let me start off by saying if this has been reposed I did a search but could not get a "how-to" on the process
So i recently got a new phone and i have my old HTC one m8, my best friend is stuck in the stone age with a very old smart phone so i said "lets make his day". Before i do though i have some questions he uses straight talk as a carrier and since the VZW htc one m8's are primary CDMA but also have a SIM card and can run off of GSM towers (yes they can only use 3g). Is it possible to run this phone off of straight talks network if so where would i start?
I guess my main questions are:
Do i need to flash a AT&T rom?
even though its a vzw phone do i need to flash new radios?
do i need to alter my CID?
The phone is S-offed and rooted!
My bad if this is a poorly constructed thread, just needed to ask!

It is possible to run through straight-talk (i did a lot of dev work on st earliest androids) you need to have unlocked devices and get the byop SIM card for att. Not sure what size SIM these phones take.
Also... St has no network they just lease tower usage.
Not sure about the Rom though... Never done a Verizon to att switch.
Last edit... Your data cap is far from unlimited and they're not cool with tethering. They claim unlimited but at 2gb I believe they start throttling bad and are known to cut data and service for habitual offenders *I've read but not seen*(iirc)
I've been off st/net10 for a long time so their practices could have changed. I would advise you not to go st but that's just my opinion.

You can get the straight talk verizon sim kit and pop it in your verizon m8 and your up and running, it will use verizon towers everything the same just you will have a 5mb cap on your data speed but you will get verizon LTE data and with st verizon you will get 3 full gb's of LTE data for $45 a month unl talk & text.
If you try to use at&t you will not get LTE data only hspa which hspa can go from I believe 4mb's to 12 mb's download speed. Your better off getting the st verizon sim kit and run verizon through st.

He wants to run on at&t. He was talking about the boosted att service at his work.

He mentioned that yes but I also mentioned that he would not get at&t LTE data on his verizon m8 that he would most likely only get hspa data speeds using at&t. People have worked hard getting a verizon m8 to get LTE data on tmobile some with success but most say they have to keep toggling air plane mode to keep the tmobile LTE data working, and there are very little far fewer success stories of people even getting that far with at&t LTE data on a verizon m8.
Basically the best thing is either run the straight talk verizon LTE sim card in the verizon m8 or sell off the verizon m8 and get an at&t one or a tmobile one and even then you can convert it to a dev edition and get updates faster directly from htc.
No one has figured out a way to convert a verizon m8 to a dev edition even though the verizon m8 is a world phone with cdma and gsm both, for some reason you cant because of the cdma side.

I"am running my verizon m8 on straight talk verizon service and mine works great. Does your verizon m8's imei show clean for activation with verizon ? Because if your imei is blacklisted with verizon it wont work or may for a while until their system picks it up and locks out your sim card because of it.
Its really just as simple as popping the st verizon sim in and run with it, unless your not fully activated with straight talk ? If you ported your number in it can take a day or so even and if the port has issues it may not finish until you call straight talk about it.
Any questions just ask as I have experience with straight talk and my m8 works great on it.

The whole 1-7 days on a port is a claim by them they generally stick to. Though 95% of carriers do it in 24-48hrs tops.. twice with net10 I had to finally just get a new number to get service (which included buying another unlimited card). I'm not against st/net10/AmericanMovil I just have had too many experiences like the above trying to work with their customer service.

well the full story is i got a nexus 6 still had my htc one m8 thought i would give it to my friend, i popped the verizon sim card in and tried to register it but on straight talks website it informs me that it is not a compatible device, so before my friend proceeds in adding minutes to this new sim card he wants to make sure it will work.

Oh they tried that crap with me and I didnt take no for an answer I got through to a supervisor and I explained either they restore my 30 days of unlimited service or I file a charge back with my credit card company and they changed their tune and credited my account.
They get away with doing that too many times you can also tell them you will file a complaint with the better business bureau, or even talk about turning them in for internet fraud because it is a pure case of fraud when they wont give you the service that you paid for pure and simple.
I have ported numbers to straight talk 4 or 5 times over the years and it usually took mine less than a day to go through. Many times the problem can be the wrong account number as most people think their phone number is their account number when porting to another carrier and 98% of the time its not your account number you always have to call your cell provider and ask for your account number they like it that way because when you ask for your account number they know why your asking for it and they can try to talk you out of switching to another carrier.

Did you put the imei number in on the straight talk web site ? Because their web site will tell you if its ready for activation or if its elgible for activation. You can also check your imei on one of the free imei checker web sites and it will show the status of your imei number as far as being ready for activation.

Yeah... I spent 9 days and probably 30 phone calls talking to everyone I could get to including supervisors before I finally gave up out of frustration and just bought a new card (2 different occasions 9 days total). What I've found is their biggest issue is with Sprint numbers. At&t and tmobile seem to port easier. I've never worked with Verizon through st/net10.

I did and my IMEI is clean and not blacklsited, when i go to straight talks website it says "Unfortunately, your phone is not eligible for the Bring Your Own Phone program. The good news is that Straight Talk has a large selection of phones from leading manufacturers. Find a phone in-store or online that best fits your needs." the steps i went though is. 1: clicked check your phones compatibility 2: picked the red other carrier option 3: when a pop up says " is your phone a unlocked GSM phone" i picked no, and thus got this message.
Thanks everyone for helping me out again =D

You can also activate your sim in another verizon phone then put it in the m8 or just use another clean verizon imei to order the service with. Actually straight talk is easy to port to, now porting out of them now that is a real pain and takes longer. Straight talk is not a lot of fun to deal with but if you get it set up your free and clear and shouldnt have any further issues.

Do you have a friend that has a verizon phone that takes a nano sim ? If so just use their imei number to order the sim kit from straight talk it wont matter because that is just a verification to make sure your phone will work but I assure you the verizon m8 will work with the straight talk verizon sim cards.
Another thing you could do is just buy the st verizon sim card kit off ebay or amazon then just open the account on the st web site and activate your sim card number adding it to your new st account.

I appreciate the response but I wasnt the one having issues I was simply explaining my experience and putting the SIM in a different device won't help port a number. St May have gotten better but ime over two years of their android service it's best to just change your number. Outside of porting I've never had issues with them.

Anyone using a Gear S2 3G on a different carrier than your phone?

Since VZW doesn't appear to be on board with the launch of the Gear S3 tomorrow I am looking to get it on T-Mobile.
Anyone here using an S2 3G on a different carrier than your phone? If so, how's the compatibility? Seamless? Can you receive calls made to the handset on the Gear when you leave the phone at home? Texts, etc?
I know I can connect via Bluetooth when using the devices together. I just want to be able to receive calls and texts made to the S7 when I leave it at home.
Thanks

I want the handset calls and texts to forward to the Gear when I leave the phone at home, i.e. Cycling, working out.
I pretty much want it all to work the way it would if they were on the same carrier. I don't have a problem using Gear data as a stand alone. Just want notifications to go through.

It will connect. Forwarding works, but as but what I've learned is check to see if the gear is using ur phones number or the gears number.

I have the S2 Classic SM-R735AZKAATT (for AT&T obviously) but I'd like to have it set up with T-Mobile.
Can I take this into T-Mobile and set up service? If so, anyone know how much?

Im not sure to be honest. The S2 has a, esim?, i think its called. Basically the sim is built into the device. I think that limits the carrier its tied to.

I'm not sure, either, about taking it to T-Mobile. I think you have to have ATT unlock it. Are you the original owner? My understanding it that only the original owner can unlock it. As for the cost of service on T-Mobile, if you don't have a phone on T-Mobile, it's about $19/month for unlimited calls, texts, and 500MB of data on your watch. My Note 4 is on Sprint, my S2 is on T-Mobile. It is a T-Mobile model. I'd go into a T-Mobile store and see what they say. Let us know.

Did you buy your S2 new or even refurbished off of Amazon or something? You might be able to activate it online if this is the case. I went to the T-Mobile store to activate mine, as I was buying it from a guy on Craigslist. I wanted to also make sure I could activate it. That it was paid for and so on. That worked fine in the store. I had already had a T-Mobile account for my original Gear S. When I got home, though, I had trouble connecting my S2 to my Sprint Note 4. I had to do a factory reset on the watch a couple of times to make it work. It was scary at first, because when I went to set it up, the only screen I could get to on my watch was a set up screen. I couldn't get past it. That's when I did the factory reset on the watch. And then reset it some more. Finally I was able to connect it to my Note 4. The original Gear S has a nano SIM card, so you can swap it out. The S2 has an "e-SIM" card. It's sort of hard wired into the watch, I guess. The moral of this long post is, I'd probably go into a T-Mobile store to get it set up on their service. They should also be able to help you get it connected to your phone.

Does Verizon's wearable plan consist of both a cellular and a data component? Or is talk and text only available using VoIP (data)?

NumberSync S3 on AT&T

I'm unable to get it setup on my Note4. I get the incredibly useful message "Backend error" from the AT&T site after I enter the sync code on their site.
Is this a temporary issue you think, or is it just the usual incompetence of an inept software developer who can't be bothered to give meaningful results to help narrow down the cause of an error?
Is it working for everyone else?

Yep, getting the same error message. Hope this is temporary!

I was having a similar issue. On my Gear S3 when trying to get the sync code, it kept giving an error message. Finally after 9:30 central time I was able to generate the code and get it synced. I think the system was overloaded with all the at&t pre-orders being delivered yesterday.

Anyone have AT&T S3 but linking to S7E 935F International phone? Keep trying to set up Numbersync but it connects to my wife's 935A. It won't see my phone. I am running Hydra Rom but the watch is connected with Bluetooth no problem.

For numbersync to be setup, you have to have a username for myatt for that exact phone. Then it will allow you to setup numbersync if that phone is HD voice capable.

I set it up on my Axon 7 without any problems.

Just tried again, same error message

According to AT&T International S7E (Exynos) is not compatible with LTE Frontier watch on AT&T due to no HD voice? Can use Bluetooth, but not the Numbersync. I'm pretty PO'd right now as that was why I bought it.

Anybody getting this to work yet?

I have not been able to get it to work. I am using an unlocked tmobile note 4. When I called I was told it was because it was not an at&t phone. What if I change the build prop to 910A from 910T? Would that be enough for it to work? Dont want to try and mess things up.

Hi I'm new to this forum. Like OP, I also have a Note 4 ATT LTE and had the same Numbersync error. Here is how I resolved my issue after extensive research:
1) Make sure to enable HD Voice on your phone if supported (for Note 4: Settings->More networks->Mobile networks->Mobile data->check Enhanced LTE Services (mine was unchecked)
2) Before even attempting to sync via Numbersync, make sure that your cell phone number is set as primary in My ATT account. I didn't have a primary number set, so I tried making the Gear S3's number primary (when I was prompted to add one) and it didn't work properly. So I learned it's essential your PHONE (the one you intend to connect with S3) is set as primary, NOT another phone/tablet/wearable line in your account.
3) After all the initial errors and hassles thereafter, I just reset the S3 after following my above instructions and the sync was seamless and I was up and running.
Hope this helps...it certainly worked for me!

I too have a note 4 and had no problems setting mine up with the Frontier today. So far I am loving it. It was the only one that my local store had gotten in stock. Now just trying to find out how to get the second hand to start working in the deduct face with the red second hand.

The red pointer is for the chronograph function. It does not move unless you tap it to start the chrono. Bad design in my opinion.

Soo no one here might have an iPhone they were able to get numbersync to work on with the leaked iOS app?

Has anyone got Numbersync to work on International S7E 935F?

I have number sync working with my Nexus 6P, spent about an hour in the AT&T store working with the salesperson that sold me my Frontier. He was under the belief that it was tied to IMEI numbers so he supposedly cloned my wife's IMEI number to my 6P which didn't work. I told him that I read that HD Voice/VoLTE had to be enabled and because I had a Nexus 6P that was the problem. So he called support and asked them to enable HD Voice on my line. While he was doing that I was googling, found this thread: https://forums.att.com/t5/Device-Features/Nexus-6P-No-HD-Voice-and-Wifi-Calling/td-p/4346076 and followed this guide:
Navigate to Settings > More > Cellular Networks and enable the toggle switch for "Enhanced" 4G LTE Mode. However, if the toggle is missing then follow the steps provided below:
Launch the Dialer app on your phone, and dial*#*#4636#*#*.
Choose Phone information.
Enable or select VoLTE Provisioned Flag.
Restart the phone.
Go to Settings " More " Cellular networks and toggle the switch for Enhanced 4G LTE Mode, and the HD Voice calling feature should now be activated on your device running Android 5.1 and above.

I enabled the VoLTE option, restarted my phone and sure enough when I went back into the MyATT webpage I was now offered the ability to enter in a sync code and it worked. He was never able to get support to enable HD Voice on their end. Going back into the setting it shows that VoLTE isn't active, I have no HD Voice option or feature in the Enhanced 4G LTE options at all but my number is indeed synced. I left my phone at home, walked the dogs and made 2 phone calls and the number did go over as my cell number.
Now the other thing he mentioned that should work is to use an approved AT&T phone that has HD Voice capabilities enabled. Then if I were to put my SIM in that phone, wait for the MyATT webpage to update showing that this other phone was tied to my number, then perform the number sync at this point it should also work, once it's enabled it won't go away according to the ATT rep. I didn't need to do that so I can't confirm but it sounds reasonable.

Unlock note 8 does not support LTE on AT&T

Hello,
Can you guys who have the unlock note 8 and on AT&T network confirm that it does not support LTE?
I saw a review on Best Buy stating that he could not get it to work after numerous call to tech, and AT&T suggested they buy the AT&T version and unlock it.
I just bought the unlock version from Samsung and planning on using it on AT&T, I tether a lot in my car and if LTE is not available I will probably return it.
I am not going to paid almost $1000 for a phone that does not support 4G LTE

I just bought the unlock version from Samsung and planning on using it on AT&T, I tether a lot in my car and if LTE is not available I will probably return it.
I am not going to paid almost $1000 for a phone that does not support 4G LTE

Exactly. Weird how it's not working. I had an unlocked version of the S8+ on AT&T which worked on the LTE+ network.
Composed on the Galaxy Note8

I have the factory unlocked version and I have LTE. Make sure when you activate your note they use and new sim.

Well, I am in the same boat as you. I bought unlocked directly from Samsung and put my AT&T sim from my AT&T branded S7 edge in thinking that it will just work. First I didn't even have data so I changed the APN and got data but only H+ speed at best. I did chat online at AT&T and the first time the tech said that I needed a new sim and I can get a free one at a local AT&T store. I reverted the phone back to stock without data connection and went to my local AT&T store. I told the guy there what the tech said and he took my phone and just mucked around with it and got data connection but only H+. He said it is probably the best this phone can do. I am like ??? But I didn't argue with him and left. I again went on chat at AT&T website and the tech did something on her end and eventually open a case for me. I waited 2 days and finally got an email saying that it is the area that I am in and that would be the best signal I will get. Again what the ????. I had LTE all along in the past at the same place, home. So after 2 more days, I again did chat with AT&T and this tech basically said I needed a new sim and he will send one to me for free. So now I am waiting for the new sim and hopefully with the new sim, I can register the sim with my IMEI and get LTE back. You should probably save all this trouble and ask for a new sim to start with. Good luck.

i got the unlocked verizon variant and switched to att and i kept getting h+ i then flashed XAA rom same thing if you want to get all the features and the actualy 4g + like i have now you need to flash the rom wont void warranty and legit i can send you directions how if you want took me a day and a half of searching and trials

Thanks Xenshen, I think that will be my last resort. You said unlocked verizon variant, what is that? There is unlocked and there is branded unlocked directly from Samsung. My is not even branded. I guess either way works with flashing. Would love to get the direction if you don't mind. I will save it for the last resort after I try a new sim.

all Verizon phones are unlocked without the bootloader being able to be unlocked but if your flashing carrier firmware you can go from any carrier without voiding warranties and messing your phone up. The unlocked one from samsung just comes without the bloatware and from what ive read its still bootloader locked as well because of the snapdragon chipset in it. But if you put the att rom on it you wont have a issue and will get all the features including the lte enhanced services and all

ive flashed 3 different roms on it now so seems to be just like the s8 where all US models are the same minus the carrier oh and i removed most the bloat and just disbaled the apps i wont use

Well all I had to do is put in the sim from my V20, add the NXTGENPHONE APN and it was game on immediately.

The new sim will fix your problem. The old sim was connected to other phone imei.

I had the same issue
I received my phone last week and I was also having LTE problem. At first it was no service, then after some apn configs I was getting H, and H+ speeds. I had talked to multiple ATT reps and most said I would have to wait until they released the phone for it to be seem in there system. Since it was realeased on the 15th and the update came today, I thought it would fix it. It did not so I called ATT again. after about forty mins on the phone and many restarts later we finally got it to work. I now have LTE and LTE+ for ATT on my unlocked SM-n950u1 .

I think he said something along the lines of, " It's permissions were defaulting to 3g," or something similar. He may have also removed my device and re added it. He also mentioned that he was getting permission from a supervisor to make an official report since it seems to not be an isolated incident.

Attached is the post on best buy I was referring to, that's why I was scared since I have already ordered it.
But glad to hear it works and should work just like the locked version for LTE.

Getting the unlocked today, will goto local AT&T store and get a new sim card first thing. I will let you know how it goes.

s3 frontier with att and s8 galaxy unlocked phone numbersync is a no go?

I spent over 2 hours last nite with att reps trying to enable numbersync to work between the s3 and s8 phones.. the s8 phone is an unlocked phone (not bought through att), only to find out today via another rep that the phone must be bought via ATT or truly att branded.. which i find a bit absurd, as i think others have succeeded..
Is this really the case.. anyone know or have this same experience?
Specifically this error would appear after going through the get started via the watch then on the phone (after creating a seperate accessid):
Oh darn! We can't enable device syncing on this phone. Want to find out more? Call us at 800.331.0500 so we can help.
(MSSITWINREL12)
If this turns out to really be an unlocked phone issue (which is a bit ridiculous), i think i read that it might be possible to take my sim card out of that phone and put in another phone that is att branded, enable number sync then put the card back in my s8 and go from there
Thanks

The phone does not have to be AT&T branded, I have a T-Mobile Note 4 and until the last update numbersync worked. Updated my S# over the weekend after avoiding it for as long as possible, and now numbersync is no longer an option on my S3.

Thanks for the reply.. your saying you had an unlocked tmobile phone on att and it was working till a recent tizen update then?
The rep further told me to take the phone to the best buy samsung experience store and have it flashed with the att firmware to get around this issue.. maybe not needed then? (which i assume means a wipe and possibly lose my unlock)

I had the same problem with my Gear S3 and my Axon 7. Worked on for a solid hour with an ATT rep in store and another hour on phone with someone else. Finally it was determined that it wouldn't work on an unlocked phone. Haven't tried the sim swap with an ATT branded device yet, but if I do, I'll let you know if it works.

Spoke to an att rep again today who called me.. basically in my case the 950U1 s8 phone.. because its this model it wont work with numbersync they say.. they also contradicted the previous reps suggestion of taking the phone to the samsung experience place and having the att firmware flashed on it (or doing it at home).. saying it wont help.. that they need HD voice provisioned and it wont let them provision it (the phone wont).. they said swapping the sim card to a real att phone only may help for a short period, till the system does a sweep, sees a non att phone and reverts it (same with just adding the imei to the database).. There is also a good chance the recent update to either the s3 or the samsung s8 caused numbersync to do a detection for unlocked phones and not allow this (they indicated).
They said i could still try doing the firmware flash but it probably wouldnt work (i dug around online trying to find out which flash it would be and i didnt get too far, short of going to the store to do it at best buy samsung experience)
Really sucks, as the alternative, if i were that desperate to enable this feature (i dont think i am willing to go this far) would be to sell the old phones and get new att branded ones.. end up costing me the price of a new watch in the mix just to do that

When I first bought the watch it was for the numbersync feature. My first problem was even though the Samsung rep and the bestbuy rep said that it would work with my Note3, it did not. took several calls and many hours of trying to figure out the HD Voice (VOlte) provisioning. Bought a TMobile Note 4, rooted and rom'ed this worked to setup numbersync. the only problem was it would occasionally turn off numbersync, this occurred about once a month. Then if failed completely said that this line is not accceptabl;e for numbersync. this was after about six months. Discovered that it appeared to be age of firmware related, I was on a TM firmware that was several updates out of date. When I odin flashed the latest firmware numbersync worked again until the recent update to 3.0.0.1 on the gear firmware. Now I have the line not acceptable for numbersync again. I'm going to try to update firmware again to see if that works. If not I will probably look to change carriers to TM. will cost the price of a new watch, but will get me out of AT&Ts locked boot loader.
BTW, setting up numbersync on a different phone and switching back will not work, Tried several times and as soon as you turn on the phone that is not HD Voice capable with your SIM card in it the system sees it and turns off numbersync almost instantly. went throught that trying to get my Note 3 to work.
In all my experience the Samsung and AT&T reps were not a good resource. Numbersync does not appear to be a very popular feature and they do not know much about it.

My main motivation for it has been that.. someone correct me if this isnt accurate.. if your phone dies or is off.. when you dial someone from the watch or text them it will still show the cell phone phone number, not the watch phone number as it does now if bluetooth isnt on.
I'm in the process of gathering the files i need to do the att firmware flash and hopefully hd voice works then (as others say it has).

Yes, that is the whole point of numbersync. The watch uses the phones number not it's own.
Tried updating to the latest firmware and a ROM based on it. No luck still get a rather comical response "Oh darn! We can't enable device syncing on this phone. " worked until the tisen update.

There also seems to be confusion on numbersync with the att reps.. one person told me the watches dont need their own numbers.. that numbersync is all we need (but how would the watch make a call if the phone is off).. another said yes they need external numbers for number sync or solo
edit: i see your last post.. so the latest reps are correct then.... so they assigned us numbers and $10 access fees each with activation fees for no reason basically.. ugh

The watch has to have it's own number, that is it's address on the network. Without it numbersync would have no way to send calls to it. Same as with the LTE enabled iPads they could not make a call, but had to have an address on the cellular network.

Just a quick note...i too spent 3 hours in an AT&T store trying to get numbersync to work..., finally returned the S3 Frontier cancelled the number in it and left frustrated...i now have a GS8 unlocked on AT&T through my work...that is synced to a Verizon Gear S3 Classic lte and i simply use call forwarding with YouMail. If i do not answer my phone after 3 rings it gets sent to my watch and if I still do not answer then Youmail picks it up..If I call out or text with the watch separately then I just let my customers know that I have 2 numbers 1 for my cell and one for their watch. I just don't think AT&T is ready for the Numbnersync technology yet and they just don't care enough to train their own people on it, sad as it is a good promise...

I meant phone number.. are you saying phone number? After the rep said i didnt need a phone number for each watch, she credited me back the cost of the two lines and said just to contact them that they would enable the numbersync once i had the phones ready.. I'm assuming number means imei, which they still have in the system.

Yes each watch has to have it's own phone number. I believe this is another case of AT&T rep not understanding number sync.

I managed to firmware update so that i have the att bloatware (didnt even need reset, all software was kept).. i confirmed HD voice is working but WiFi calling throws an error to contact ATT.. hd voice was the key for numbersync.. however.. despite this.. and 2 hours on the chat line with ATT.. i still get an error when you do the s3's get started numsync and it opens the page on the phone.. the oops, device sync cant work with your phone (which went from a 950U1 to a 950U btw, which is good as well).. They escalated to another backend team, but i highly doubt they will get it working.. most likely they'll still complain that my phone (was) an unlocked phone, despite adding the att firmware to it.

Update here.. i managed to get everything working by going with a new sim card.. wifi calling works now.. and i was able to complete numbersync setup.. the only remaining issue i have is that my callerid seems to be blocked on the receiving end.

With the Firmware did you have to go through the full process where you changed the CSC and flashed the ATT firmware? Currently I am running a Sprint phone that is unlocked an running the US Unlocked firmware. Even running the ATT firmware they still were not able to get HD Voice or WiFi calling working for me.

The full steps, or mostly full.. are here in this thread..
The short of it was that i only ran regular odin at first.. just did HOME_CSC (using the verizon firmware which covers all carriers).. then rebooted the phone and did all the check boxes and the regular CSC.. after rebooting nothing was wiped and att bloatware was there... at this point hd voice was working.. wifi calling wasnt.. so i went to the store, got a new sim card today, then wifi calling was working.. numbersync took the code on the phone without error.. however.. now i'm realizing it isnt really working.. when i turned the phone off, and texted, it showed my s3 phone number.. and my callerid is still botched.. i think att botched something in this whole process.. so yet another call to them needed.

Thanks. It sounds like the latest firmware they did seems to fix some of the issues from bringing a non-ATT phone over but does not resolve everything. It looks like I won't be able to do this though. ATT and the ebay seller are unable to clear the ICCID on my watch, I have to sadly do a return now.

Kinda unrelated, yet ATT was horrible even for normal Sammy phone/watch. After dumping ATT service/hardware for various reasons a few moths back... Sammy watch/phone from Verizon hardware/service works flawlessly. Am carrier neutral, but one works reliably, one didn't.
BTW, Sammy pay via watch hiccuped via ATT at times, yet works flawless via Verizon.

well 5 chat people later they finally fixed the unknown callerid issue.. apparently there is an internal back end feature for numbersync regarding it set to active and on.. both toggles were on.. the rep removed the "on" and now my callerid shows my number when calling from my phone (and from the watch when watch is in solo mode too).. everything works! :laugh:
