[Q] HTC Merge SIM help

Hello, I bought a SIM card from straight talk hoping to use it on my merge because I have seen people online that says I can do that as long as i have my SIM card unlocked. But after I got the card activated and put it in my phone it don't work. I try changing to GSM and using their APN but I have no signal, the mobile network just stays unchecked and I cannot check it. After a few minutes my phone suggests switching over to global mode and i do have mobile signal then but still no connection with anything. I called the straight talk woman and she told me it only works with AT&T or T-Mobile phones but it just don't make any sense to me that you have to have one of those previous carious just to get them as a new carrier? Am I missing something here?

Thanks to the helpful people over at 2fastroms and their quick response I found out that you have to have the 1.06.00.0910 verizon radio flashed to your system. You have to install the radio in the boot-loader and not the recovery menu, it took me a minute to figure that one out. Just informing anyone that has the same problem as me because I could not find it anywhere else on the web. Anyway credit to jianC for the help.

[Q] Phone Thinks I Am Roaming

Hello,
I bought my HTC Sensation about a year ago on Ebay. The seller claimed the phone was purchased outright and paid off. I checked the imei and it showed clean. When I got it, I popped my Airfire sim card into it and it worked fine. A month ago, I switched to Cricket as Airfire was going out of business. Cricket made me enter my imei. It said it was bad. I called T-Mobile and they said the seller defaulted on payments. They refused to help in any way. They told me to buy the phone direct from them next time. I told them I had proof I was buying it in good faith. They didn't care and apparently have no problem punishing the victim.
Anyways, when I got my Cricket sim and popped it in, my phone said I was roaming. It has said I was roaming for a full month now. I can send and receive calls, but my data is stuck at EDGE and some of the programs don't work since the phone thinks its roaming. I need to have "data roaming" enabled for data to work. Cricket ran some tests and eventually said I needed to do a factory reset.
So, I switched from the Android Revolution rom to the ViperS 5.2.1 rom. I did a full dalvik and cache wipe and reformatted everything but the sd card. I installed the new rom and kernal. Same thing. Phone still says I am roaming. Odd thing is, when I go to manually select carrier, my options are Cricket (current carrier), Airfire (previous carrier) and TMobile (stock carrier). Also, when I am using data, it has an "E" above the data. E is what Airfire used. Is there somehow somewhere a place that the phone is storing info through wipes?
I am s-off, rooted and debranded. I sim unlocked the phone myself. I am so stuck and think that only one of the geniuses on XDA are my only hope. I have went mental spending hours and hours on this. Some XDA peeps are smarted than HTC and Cricket combined, so please help me out here.
Thanks,
Grant

Hi grant, this is a very odd situation your in. With my sensation when I leave the UK and connect to another EU "partner network" is the only time my phone would jump into roaming mode. Is it possible that cricket is not directly supported in your area? Maybe they rent their local connection from another carrier and thats why your getting connected as roaming? Have you tried any other sim cards to see if they come up as roaming?

Hi heavy_metal_man
I am quite sure that At&t is Cricket's parent company so all of the towers should be At&t's networks. Also, I have checked it when in other cities and I get the same message, though I haven't traveled more than 30 miles away.
The previous sim with AirFire worked fine. I also popped out the sim for Cricket and put it in my mom's phone to see if it was the sim. Her's worked fine. She got the automatic Cricket update settings right away and was not roaming. Mine never got the Cricket pop-up so I had to manually enter all of the data info. Yes, odd indeed and I am lost.

OK, the info your adding manually, is that the same info as is registered when the card is in your mums phone? Same APN etc?

Hi heavy_metal_man. Yup. Same info. Only difference is that the info all loads automatically on hers. I do get automated texts from Cricket when I put the sim in my phone as did she, but I had to get the APN info from Cricket the first time because it didn't auto load. I am still wondering if it is a sim issue, but I expected my mom's phone to be roaming when I put the sim in hers. I was shocked when it wasn't. She just has a free stock phone from Airfire btw. Nothing fancy and nothing done to it.

Hmm. Are those 3 carriers the only ones available to you? I think the imei may be key here, if cricket know its a T-Mobile phone they may register that you are roaming. I think your previous carrier (airfire) was a Virtual mobile network, much like giffgaff in the UK ( which runs on the o2 network.) As such they may not have inforced the same imei policy's that cricket does. But this is just a hunch as I am on UK networks and we do things much differently. If you could ask about any friends and colleges that have different carrier simcards from our previous 3 you could gauge what carriers your phone is compatible with.
Worst case scenario you could maybe buy another broken htc sensation and perform a motherboard swap. This would solve your imei issue, assuming that it was the primary issue. But check the simcards first and report back

Hmm... There are only 3 carriers available. Should there be more? It's not tied to the sim? Everyone I know either still has Airfire and plans on switching to Cricket or has cdma so I have been out of luck with trying another sim. The only other thing I thought about was 4ext recovery. No matter what I flash; roms, kernals, firmware or radios, the recovery always survives of course. So, if the previous carriers are surviving the flashes, perhaps there is a place on the phone like the recovery where they are surviving.

Its unlikely to be to do with the recovery, no reason for it to keep anything like that. It's most likely the phones imei at this point, though im unsure as to why this was not an issue for airfire.
Do you know what firmware version you have? Have you flashed 3.33 by yourself?

Yup, I flashed 3.33 universal after doing a super Cid. Well, maybe its time to just get a new phone, although I would really like to figure out this problem first. I am not the kind of person who can just drop things, lol.

I know how you feel. Maybe its because they cricket know the sensation 4g is a T-Mobile device and force you into roaming mode by default. I think its possible to overwrite the devices mid and cid, flash a sensation XE rom and effectively have a sensation XE. But such things can be quite dangerous and i couldn't say for definite if it would work to fix your issue :/ (not recommending anyone tries this without proper research and understanding :/)
Can you get access to another cricket sim without a contract? Just for testing?

I believe I have already done that. When I go into info about my phone, it says Sensation XE. It also registers as Sensation XE in the Google play store. I was thinking about telling Cricket to send me a new sim. Otherwise, I have no access to one at this time.

I think that it would be your best bet, although your device is probably showing up on the play store as an XE because of its build.prop from your custom rom, not any advanced MID changes. although you can check by using the command
Code:
fastboot getvar all
this will show your your mid, cid and your imei among other things.

I've worked it out! Its a frequency issue. Cricket apparently only support cdma frequency's, while the sensation only uses gsm frequency's. So in order to connect your phone is bunnying onto a local gsm service, which is then redirecting you to cricket. Hence the roaming! If you want off the data roaming you will need to either swap to a different phone carrier or buy a cdma phone
Sent from my Nexus 7 using Tapatalk

Hi heavy_metal_man,
Cricket did use CDMA for most of the time, but they have switched to GSM. They send a sim now and are trying to switch all of their old customers to GSM. What I am having trouble figuring out is what frequencies they use. Perhaps my phone is not quite compatible. I am having trouble with that as well. GSM arena, Phonescoop and the other major sites kind of have different data as far as my phone goes. My phone is called "HTC Sensation 4G" as far as I know. Yet, they list no 4g capability or frequencies. Of course, I believe that would only affect data and I still should not show as roaming.
I have been unable to figure out fastboot since switching to the viper rom. It doesn't use usb mass storage anymore. It uses the new system in which the whole phone is recognized as a storage device by the computer. Forgot what they called it. I wish they hadn't changed it, and apparently Windows 7 should recognize it by default, but it does not. I am sure if I get enough time to put into it I will figure out how to use the fastboot commands again.
I am ready to give up and just get a new phone pretty soon. Would be nice if Cricket's customer service wasn't so worthless. It could still be the IMEI or something on their end that I can do nothing about but they have failed to provide any solution.

Sorry for my delayed reply, I noticed that cricket swapped out to gsm and I discovered that their gsm tech is actually supplied at&t as they bought them out.
So I looked at their coverage map for the area airfire operated and I noticed that they had 2 or 3 area that were only providing 3g support via a partner, so I assume that would put you into roaming. It might be worth a look at their map and confirm if you reside on one of these black areas ?

[Q] OPO on T-Mobile - 2nd OPO, same problem - network connection issue

Hello all,
Back again.
I'm trying to get my "2nd" OPO to work on T-Mobile USA.
First of all, it is not a SIM issue. I have 2 microSIMs that can be used freely across all T-Mobile enabled devices.
Once I try to connect to T-Mobile, it gives me a "Your SIM card doesn't allow connection to this network".
I tried the 'unlock the basebands/LTE process', got as far as ADB talk, but I cannot execute the su command, so the setprop does not work.
And this is my 2nd phone, a replacement from OPO. 2nd month running already. The 1st one had the same issue, but at the time I did not do research on tinkering with it,
and was 'NAIVELY' believing in OPO's customer 'service'.
Took me 2 weeks just to get 2 basic replies of "tech support", which didn't help since they gave me rather weak tech suggestions - 1st suggestion was reset, 2nd suggestion
was to look at the T-Mobile thread (I cannot connect to network, so how do you expect me to connect to APN?!?) . Then took them 3 weeks to go through the RMA process,
and yet another 2 weeks to send me a replacement(not).
Any assistance appreciated.

Check your imei on the tmo compatibility site. It could be blocked. Dumber things have happened. Double check that the SIM is installed properly. Second replacement and multiple sims seems to point at something you are doing.

Thank you for your response!
Yes, the IMEI is not recognized on t-mobile. Which is stupid since this is the second one (the 1st one had the same issue too).
Has anyone else gone through this frustrating experience? To have two OPOs whose IMEIs are not recognized is...... well.... $!%#!. :silly:
SIM installations are fine. I have done them multiple times, with the same results.

Future reference no need to create a new thread to ask the same question as before. You should of just continued your first thread so others would know what you have been going through and what was done to try and fix it. Glad you got it sorted or did you....

Got it.
Unfortunately no. Second OPO, same issues again. IMEI is not supported either. So, Groundhog Day here.

I'm with you man. I left vzw for T-Mobile and struggled like hell with getting the OPO working properly on it. From loaner phones to multiple sims, they/we tried everything. End result was to leave for at& . The signal is strong, but yet I keep missing calls daily. This beauty is going up on eBay. I just can't take it anymore. Sucks because Dev involvement is Huge here

Register and activate your phone with T-Mobile... I had the same issues for MetroPCS, and that fixed it.

I dont have any issues with network on Tmo, but what do u mean by register and activate ?

What I am saying is, you need to contact your carrier and get your IMEI entered into their system in order for the phone to run all services correctly on your carrier... whether it be T-Mobile or anybody else.
My 1+1 ran most of the services and operated on my SIM card and phone number in my hometown area. But, when I went to another area or town, it would not register with or run on any carrier... NONE! not even roaming like it does at home. I had to go to MetroPCS (on T-Mo network) and get my phone activated onto their system for it to run data, and 4G LTE. By just inserting the SIM card does not automatically sign your phone into the system and you should call or go to a dealer store and get it turned onto your particular carrier to run the network correctly.
Hope this clarifies my statement.

I never had to register or the like with my OPO for t-mobile. Didn't have to with my wife's OPO either.

It's a common enough issue across carriers. Sometime you do have to register the phone, and make sure you have the correct APN settings.
I just gave my daughter my OPO, I had Consumer Cellular (ATT) SIM in it. She dropped in her T-Mobile SIM and off she went, working perfectly. She's been using the phone about 2 weeks now, and in response to your question, I just checked her aPN, since I knew it's been working perfectly for her, only to discover the phone pulled in a MetroPCS APN! It's been working so well, she doesn't want me to change it to the T-Mobile APNs that are in the list.
Here is her APN settings (Calif-San Diego area), MetroPCS
name MetroPCS LTE
apn fast.metropcs.com
MMSC http://metorpcs.mmsmvno.com/mms/wapenc
mcc 310
mnc 260

What APN is you OPO set to?

I had just popped in the SIM card and it did work in my local area. But when I went outta town, my phone wouldn't connect to any services, no roaming either. I use MetroPCS on T-Mobile network, and nothing would run without activation on their system and registering the IMEI. So, results may vary depending on the carrier or area.

registering
I am a frequent visitor to the USA from Canada. Usually with my original Samsung or Nexus rdware from Canadian carriers, but unlocked.
Each US carrier has insisted on registering my IMEI prior to activating a SIM. It seems to the user you can pull a SIM and place in any old device and most times, no problem. But that's not the carrier approved method.
T-MO was very insistent on this. To the point they would not activate a SIM for me with out the device and the IMEI first
Hopefully registering with your carrier solves this. It's a thing and may be the point of issue for you.

[Q] Bought used phone, won't activate with new sim from verizon

Hey M8 crew!
New to the M8, just bought the phone from swappa. Apparently it has root/s-off/some lollipop build installed on it. Clean ESN.
Took it into verizon to activate it on my line, but the sim doesn't appear to activate as they expect. It detects that it was inserted, says to reboot, after reboot still says no service, and never performs any activation. Verizon rep was claiming that the rom was causing the failures, and it does appear to likely be software related if it is never launching the activation. VZW tech support was no help other than saying it may take up to 12 hours to activate the sim (bs meter going off). Spent 2 hours in the store trying to get it to activate, saying everything was fine on their end. Tried a couple sims in store to rule out a bad sim. Have even tried the tape on the sim trick to see if that might have something to do with it.
Has anyone ever seen / heard of this sort of situation before and have any idea of how to fix it?
Would a stock RUU flash help out in anyway?
Is it because it is not a verizon rom that the activation is not happening? Would I somehow be able to use a different verizon phone to activate the sim, then put it in my phone and have service start working?
Any ideas?

If the phone was used on another carrier it might be stuck in a non lte/CDMA mode. Flash stock vzw ruu. Do a factory reset. Go into mobile settings and make sure it's set to global. Then see if default network is set to vzw. Then check provisioning.

That did it. Thanks!

Question Can't remove old Carrier's information on Global Unlocked phone

Hi all,
I have been stay up two days to looking for my solutions and would you guys at least let me know if this is impossible or possible?
1. Bought Global Unlocked AT&T phone from my friend. When he sold it to me, I made sure it is unlocked and move to any carriers.
2. I check IMEI numbers and everything from Verizon (I called them) they confirmed this phone is compatible in their netowrk and will work.
3. I switch my iphone 11 max pro sim card (verison) and put it to Samsung Z flip 3 5g.
4. Everything works find but, I saw AT&T logo when I start the phone. I also some of AT&T setting's everywhere. I did factory format and showing the same thing.
5. I called verzion and they said, because I use 4g sim to 5g phone and asked me to visit their direct retailer to get free 5g sim card and I did.
6. HOWEVER, after change even sim, it shows still AT&T logo and AT&T related menu in the settings and everywhere. Also, I did not even have wifi calling feaatures.
6. After that I have been search and study two days but, still couldnt' figure out what's going on. What I found is I need ask my current carrier to push OTA. (that's the one of other people suggested and I did chat with verizon and they said, they will get back to me after senior engineer to check if they can do it.
7. They also make sure my phone is registered their networks and works fine.
It is really bothering me to see some of AT&T settings still turn on and also shwoing in this phone.
Probably this phone is global unlocked phones provided from AT&T from the beginning.
While i am searching and reading the articles, lots of people told me to gave up because i am even on Verizon, they said I have to depends on AT&T's OTA updates and etc....
it is my fault to bought it from my friend even tho I belived that because it worked, I thoguht that everyhthing would be fine......
What should I have to do? Just stay with it and sell it when z flip 4 is come out? Do I really didn't have any change to correct this issue?
I was fan of iphone and i swiched to android first in my life and everything went wrong. I want to fix and stay on Samsung. Would you guys can at least let me know there's no way or there's way to correct this so that at least I can ignore everthing and stop trying to find answer all day wrong........
Thank you and sorry for long question... you guys are my last hope.
Thank you in advance.
Respectfully,
