Sim Free vs Branded Moto G - 3G Signal loss!

Hi,
I have a Vodaphone branded UK Moto G - I have just unlocked it successfully and flashed the stock FW. My friend has a Sim free Moto G. I was concerned because on my Moto G I cannot get 3G signal in the house, all I get is "G" rather than "3G/H+"
Using the same sim in my friends Sim Free Moto G, I can get H+ very eassily in the same house when the phone are placed still on a desk.
Does anyone know why this might be? I'd like to know if it's worth me getting mine replaced first before taking it back and paying the extra for a sim free model?
thanks

Check if you're on 3G or 2G in settings

Are both devices on the same modem version?

They both seem to be identical in software (in the about phone section)
And the only visible difference is the back of the branded
One has a white M rather than black.

I don't know if this will solve your issue but download phone testing from diewland from playstore and set your network to "WCDMA ONLY" and see if it helps. If not it might need to reconfigure your apn.

You can check/select the network type by going to the dialer and dialing *#*#4636#*#* and looking in the phone information section

droid ultra 4.4.4 not working for tmobile

2 months ago a friend of mine bought himself a bad esn motorola droid ultra for Verizon carrier on ebay and it works for T-mobile and AT&T just fine. His droid ultra was running stock android 4.2.2. Just recently I bought myself a bad esn motorola droid ultra for verizon on craigslist that's running android 4.4.4. I'm with T-mobile service, but I like verizon phones so I bought it thinking that it would work for T-mobile. Unfortunately to my surprise when I put in my T-mobile nano simcard, I notice that for the first 2 seconds it would seem like it's connecting because I can see two white bars then all of a sudden it would vanish. And all I see is a black triangle with dark-gray lines next to the wifi signal indicator, and not only that but I would also see something that reads: RESTRICTED ACCESS CHANGED on the upper top left corner. I tried changing the settings to GSM only and still that doesn't work. I tried using the Phone Info app to tweak the settings and still that doesn't work. So my best guesses are 1) sim tray is bad. 2) it has a bad esn so verizon blocked the phone from being used because an Apple tech person told me that Verizon, T-mobile, and AT&T shares one database where they keep and block all bad esn phones. 3) Motorola disabled the gsm radio on the 4.4.4 android update because Verizon didn't want people on T-mobile service using this particular droid ultra phone on the T-mobile network, so that's why Motorola was so quick to release the 4.4.4 android update for it. Well what other reasons for it not working for T-mobile I don't know. I guess I'm stuck with a giant ipod-touch like android media player. Any suggestions on how to get T-mobile to work on it would be great.

The Sim may be bad. My tmo Sim just went bad.

Just went tried it with an AT&T nano sim-card from my brother's iphone 5, and the droid ultra was able to pick up signal; and make phone calls and send text messages right off the bat. I figure it could be my T-mobile card so I went and bought a regular standard size T-mobile sim-card, and had it trim down into a nano size sim-card; but unfortunately it still wouldn't work. So my guess is that in order for the droid ultra to recognize the T-mobile sim-card it has to be an original nano sim-card. I will go to Tmobile store and buy a nano sim-card and see if it will make any difference. Thanks for your suggestion.

Dude any bad esn from verizon is not going to work with tmobile anymore. T-Mobile and verizon now share block list. At&t doesn't share verizon's bad imei thats why it works with at&t. Before Verizon bad esn phones worked with T-Mobile now it doesn't.

AT&T APN Settings for UK Version used in US

I have the UK Version, trying to use it in the US on AT&T. If I did my research correctly, the phone can support 3 out of AT&T's 4 lte bands, but I'm only getting the H and H+ icon. I know that in the UK, the 4g icon means lte, but I'm pretty sure that H and H+ mean HSPA and HSPA+, not LTE. Is there anybody in a similar situation that is able to get 4g? And if so, do you mind posting your APN settings, or the steps that you took to enable 4g on the phone?

Mine shows 4G/4G+ (which is LTE).... The only bummer here's that it's super low where I live. I know my previous OP3T got higher service bars but right now I'm fine because I use WiFi 99% of the time. The settings I use are for the ATT PRODATA apn (you could just search for those settings on Google) and the phone also set to 4G preferred under mobile network settings. Hope that helps

Is your IMEI on your AT&T account your XZP one? If so, that's your problem. I went through that already. I had support switch it to my Pixel and instantly got LTE on my XZP.

I wonder why that's the case. My previous phone was an unlocked verizon lg g3, which didn't have all the lte bands on the phone. I'll have to try w a friend's sim or something and see I get lte then. That's the only way I know to test this.

Who knows? I have the G8142 model. Perhaps they weren't a fan of it. I was on AT&T years ago with my OPO and Nexus 5 and had no problems (signed with Nexus 5 IMEI). I switched to Fi then until a few weeks ago when I switched back.
I spent days trying different APNs and toggling data connections. I couldn't get anything. I even tried putting the sim back in Pixel and couldn't get LTE. I found a thread from years ago on AT&T's website about a guy having the same issue. I did the chat support on their website and asked they guy to switch my IMEI and gave him my Pixel one. I restarted both phones and got LTE and both of them almost immediately after he did it (while still in chat).

I just found my old at&t g3. If I ask them to change the imei on the account to this one, will they do it, or should I play dumb and just act like the imei is wrong and ask them to check it?

I told the chat dude that I couldn't get LTE and I was pretty sure it was because my IMEI wasn't an official AT&T phone. He said that was probably why and I asked if he could switch the IMEI for me and he said yes, then I gave him the new one.
You could always say something along the lines of your phone breaking and just need to switch to an older phone for the time being, then ask if they can change the IMEI.

I just had them switch it back to my G3, you were right in that they thought for some reason it was a 2g phone, the rep confirmed that AT&T is now sending data on their end, but I'm still not getting it on my end. Would you mind posting your preferred network type, and apn settings?

Not a problem. Glad it worked! :good:

Does LTE not show up in the status bar for you? I have the international model as well and LTE often shows above the signal in the status bar. I also still have my Z5P, I factory reset the device and had a different AT&T sim added to my account and put in and there was no connection. One of the reps added APN settings and it started working, but it only shows H,H+,4G, or 4G+ and not LTE. I don't have it with me right now so I can't check the differences between the settings right now.

If you have the G8141, when it displays 4G/4G+, it means you're connected to LTE. This threw me off at first too because I'm not used to seeing that.

I don't think there are differences like that between the two models, I have the G8142 and LTE shows very often above the status bar. It sounds like your APN settings may not have been correct during the provisioning process.

So far from what I'm seeing around here on the forums, the G8142 does actually show LTE whereas the G8141 shows 4G rather than LTE. You can actually verify this by downloading the app Cellmapper which will show you which towers you're connected to, which frequency band you're using and which connection type you're using.
Trust me, I went through this process already because everyone with the UK model (like me) shows 4G and everyone with the Dual SIM shows LTE. Another forum member explained to me that this is because of market differences in the UK being that they don't advertise LTE but rather only 4G (which is actually more accurate with regards to the connection type).

4G and LTE are the same thing internationally. Some regions on Sony firmware call LTE by different names- for example the Nordic firmware calls it 4G while central Europe 1 calls it LTE.

Ya, ignore what I said earlier about the APN settings, I fixed them but LTE is not showing up in my Z5P, it's still only 4G/4G+. I originally thought that I had the Central Europe ROM on the Z5P but I did a factory reset and it seems to be something else based on the default language, but I can't figure out which one it is. Anyway another difference I see between the XZP ROMs is that the US ROM has more signal bars than the one on my XZP, can someone let me know how to find what ROM I have since the build number is the same for each of them it seems?

Sounds like you have the UK ROM. Mine does both of the things you mention. Usually only 2 bars and shows 4G/4G+ when I'm connected to LTE. However, the signal bars thing may actually be due to poor signal because in some areas around where I live, I will actually get full bars of 4G/4G+
Sent from my G8141 using Tapatalk

If the UK ROM does not show LTE it's not the one that I have. I was saying LTE shows up on my XZP but not my Z5P, I think my Z5P was from Taiwan but I'm not sure, I bought it on Amazon. My wife has the US XZP and that's the one I was comparing the amount of signal bars with. I would still like to know how to actually view what region firmware is installed though, I haven't found a good answer anywhere yet.

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

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

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.

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.

LTE not functioning on AT&T

I've changed access point to the right settings and I still only get HSPA connection. I've searched other things online but nothing. Spoke to 3 reps. It says that LTE bands are supported so how do I get the best settings to get things running right? I've conveyed to international and the phone is totally unlocked. Sim and bootloader both. Am I missing something?
Thanks.

I'm currently visiting my wife in the USA and LTE is working fine for me on my 7 Pro 5G. Google the APN settings.

I did. I think maybe since it's not 5G version perhaps. At any rate I've gotten a fix the rep did.... Activated on another device like galaxy s10 then put back into my phone. I have LTE now since we've tricked the system

Also They are telling me they need to enter the imei range for all oneplus 7 pro phones which takes about 2 weeks. So hopefully the system won't figure out I'm using something other then S10 ?

Rubbish perhaps but that's what they've told me and until the rep did the trick to my sim, only got 3G. Maybe this temporary thing will be perm since he said for his Android the system thinks it's iPhone 7

I'm on AT&T with my OnePlus 7 pro and out of the box with my sim it works like a charm.
Currently "VOLTE" is displayed on top of the phone and I'm getting good data speeds (will post shortly)
I'd say something wrong on your sim or account end.

Same here. I got my 7 Pro (US unlocked version - not 5G) on June 10. Simply put my AT&T SIM in, and it works perfectly on LTE. Did not need to enter APN info, or anything.

At any rate I've gotten a fix the rep did.... Activated on another device like galaxy s10 then put back into my phone. I have LTE now since we've tricked the system

That is pretty good of the rep to work out some solution. They could have just said "We don't support your device."

Over the years, I have used several international phones on AT&T. The issue is if you establish a new line on a new sim card, lte must be "provisioned" (their term not mine).
To provision the new sim card for lte, we need to put it into an AT&T branded phone first to activate the lte, or call customer service and give them an imei from an AT&T branded phone. Once the sim card is provisioned for lte it can be moved from phone to phone no problem.
For that reason, I still keep my AT&T Galaxy Note 2 around. Anytime I get a new AT&T sim card, I put it into the Note 2, wait until I see it has lte service then it's good to use in any international phone.
