So I have 4G radio on my unit and grabbed a SIM from US mobile but they don't like my IMEI. I've been looking at changer tools to make the thing appear as a Samsung or something but thought I'd ask here first. Has anyone enabled their unit on cellular in the US? I can't find a provider that will accept my IMEI.
Figured it out.
I got an IMEI changer from TEYES and turned my head unit into a "Pixel 5"

I talk to us cellular a few weeks ago and they said I could activate a HTC touch Pro without the data package. Well, I bought one on ebay and went to activate the phone and then they said I had to have a data package. Is there anyway to activate the htc touch pro as a phone only? I would still like to use the wifi, gps and and sync my calendar to my computer. I tried to find info on the web but have found nothing that really helped me.
I think US Cellular is a CDMA network, which means, unlike GSM where you just swap the SIM card from an existing phone, US Cellular actually has to activate your phone for you for your account to be active. So this isn't really a phone issue, its really a matter of whether US Cellular will permit you to use a smartphone w/o a data plan.
Call back a few times asking the same thing, sometimes different customer service reps will give you different answers/service.
Yes, us cellular reps seems to give different answers and it is a CDMA. Is it possible to activate the phone without them knowing it is a smart phone and just activate the phone option. I would need to know how to activate the phone before hand and know what option I need to fill out. I would give them the dec number and than ask for the number I need to make the phone work.
Not sure if this rings true for CDMA, but the IMEI number for GSM phones identify each phone uniquely (manufacturer, model, plus unique code for each phone). So if you need to give them a similiar number for a CDMA phone (its called the ESN number I think), they'll know right away if its a smartphone (if they cared to look it up).
Best bet is probably keep calling until you get a nice rep that won't ask too many questions.

Hi All,
Taken delivery of a new one plus one today. Delivered and shipped by Amazon, but supplied by a company in China.
All elements of the phone work except the cellular. (wifi is fine)
Followed all the You tube clips to ensure sim is plugged in the right way. (i did manage to receive 1 message regarding a vm - thats all.)
No Cellular. BTW its on Orange / EE . In the settings the hardware does not appear to have the radio switched on.
Also no IMEI....
Does any one know if this can be fixed from a software perspective ?
I have upgraded other phones in the past but no experience with this one.
Any help greatly appreciated otherwise its going back to Amazon....
Thanks all.
Hi,
Try to look for a tutorial how to modify IMEI on android. I had a case with another phone similar issue. Just googled how to modify IMEI, entered one from back plate and it worked.

Is that not illegal?
is your carrier using wcdma or FDD-LTE? if so the chinese version has a network lock on these bands which I believe can be easily unlocked.
TL;DR: Why would my phone serial number in the setting/cover not match? Could it result in problems with connectivity or mobile data I am experiencing?
Longer version:
My phone (SM-870A) worked fine in Europe but in South Korea has trouble with mobile data (everything else is ok). My provider couldn't figure out what's wrong, so after the engineer at the service center couldn't, neither, I sent it to main Samsung service center / factory and they are telling me that they identified the problem: my phone's serial number doesn't match the the on the battery cover. (IMEI numbers DO match; I also verified this myself because they sent me photos of the back cover and from the phone's menu). They seem reluctant/unable to fix anything, and are suggesting I contact the seller of the phone for further explanation/warranty.
I tried googling, but I couldn't find out much about why a non-matching serial numbers could be related to connectivity problem, or what could it mean for the phone (perhaps it was refurbished? I was told I the phone is new, but a former unused display model... through it came already with the OS updated to the newest version). I am sure the phone is running unrooted stock ROM..
Do you think I got scammed in Europe by the original seller, or is the service center in Korea being lazy/under informed and cannot identify the real problem?
LEAD up to my question.
I have a Samsung unlocked Galaxy S9 Plus, which AT&T blocks features (Wi-Fi calling, HD Voice, visual voicemail, spam blocking built into the browser, and video calling) on devices not purchased from AT&T. in order to get these features working, someone in another forum found that if you asked the 611 ATT rep to change your IMEI number to one that is allowed to enable all features on their system, you were good to go. I gave AT&T an IMEI number off a working device (My ATT s8+, not being used) that supports those features. They all worked instantly now on my s9+ without even a restart.
The problem (potentially) is I gave them the IMEI number to my perfect Galaxy S8 Plus. I just recently requested Sim unlock from AT&T and got it approved. So it's like the perfect backup phone, not a scratch on it.
And Now, to my question...
What happens when the same IMEI is used on two different phones? I did install a Verizon sim in my S8 and made a phone call just to test that the unlock worked, but that's about it. Would issue only arise if I had the S8 on the same network as the S9 (same IMEI in AT&T's system) Or does it just not work like that and I won't have a problem? I just don't know how IMEI works., forums don't normally let you post IMEI numbers so I'm assuming it's not something that means nothing. Anyone have any ideas on what kind of problems I'll be looking at with this arrangement? And any ideas to rectify it if there is going to be an issue? Thanks so much IMEI gurus
Pardon my noobness, I will explain this to the best of my abilities
AT&T told me that my current phone Samsung S8+ will not work on their network (international dual sim unlocked version). They said that it is because "the 3G will shut off" but this phone is clearly a 4G phone. To be more specific, my device is a SM-G955FD. They sent me a replacement phone which is less than crappy and said my current sim will be deactivated soon.
I have already rooted (and ROM'ed) my phone - and I know you can change device identity/fingerprint using build props. I want to mask my phone as a SM-G955FU which is the USA unlocked version. At this point, I'd like to know if this could make a difference and make my phone not be deactivated by fooling their system, or if there are other things to try.

Help appreciated,
I don't think they query device's brand / model property as stored in Android's build.prop file because these characteristics at any time can get changed by user.
The speed of data access relies on two things: your phone and your service provider. Every phone has a radio module that is responsible for talking to the network. It is this piece of hardware that either can or can not use latest communication technologies: if the phone does not support 4G, you will not get that speed whatever you try.

Thanks, what is odd is that it should support it on several bands
Will Samsung Galaxy S8+ work in USA?
In this page we are going to show you the compatibility of Samsung Galaxy S8+ with the mobile networks of USA and with the telephony operators that provide service in USA.

The same thing happened to me today, woke up to a sim not registered message and no cell service (voice, sms or data).
I went to the store and they said my unlocked Moto G7 Power (XT1955-2) is not supported/compatible on ATT's network. I re-checked the phone's specs and it supports 4G LTE on bands 12 and 17 on 1900 Mhz which overlaps the data I found for ATT's network. I'm not well versed in this stuff tho. Perhaps it's a local towers thing and I am in an area where their towers are operating on the other ATT frequencies (1700, 700)? The guy at the store did something (I forget the exact details) and I do have voice back, but that is it, no data or SMS. He also mentioned that ATT is like cracking down on what kind of devices can connect. If ATT is blocking my device tho I'm curious, how is it possible? I guess they can lookup my device via the IMEI and then see if it's on their approve list of devices?
I don't understand their problem. Your phone model is listed as supported as long as you update your software to enable WiFi calling (VoLTE). Come 2/2022, you phone must either be 5G or VoLTE calling enabled to be supported. My Xiaomi Mi Mix 2s shows that it can do VoLTE under the sim card details in Settings and supports 13 LTE bands, including AT&T's bands. It should continue to work on their network after 2/2022.
Yet AT&T repeatedly disabled my phone. I had to tell them to re-activate my phone multiple times. I have tried some new phones. Turned out everytime I pulled the sim out to try a new phone and stick it back in my old phone, AT&T would check the phone's IMEI again and would disable the phone. On the 5th call with them, they put in a code/note in their system to mark my IMEI (be ware each sim tray has its own IMEI) not to be disabled until Fed 2022. I have since tried Surface Duo which on this list and decided not to keep it. Stuck the sim card back in my old phone specific sim tray and it continues to work.
Call them to re-activate/keep your phone active until Fed 2022. They have no rights to disable your phone before then.
Most A&T reps understand less than us on the reason to disable our phone. They jsut keep saying 3G phones will be disabled but our phoens are clearly LTE. VoLTE is one real reason of the problem but them our phones support VoLTE anyway. I am tired of arguing with them and am looking at a Note 10 now. But your situation got me concerned. Sounds like they may not honor the supported list which is updated frequently. I downloaded the June version of the list which is largely the same as yours and asked them how long they would support the phones on the list. They couldn't/wouldn't commit. Even on the phones they sell at their website, they would only give a vague promise to support them for "quite a while".
AT&T has always advertized BYOP. We spent big money on nice phones that are compatible with their network. And now the want to shut us out.
