I have a Cobalt SP300 I bought on eBay. It has a MT6575 SoC that has a 3G radio integrated according to the manufacturer. I know other phones like the Zopo 100 with this same chip can access 3G bands of 850/1900 mhz. I looked up the IMEI number on some websites and it shows it to be a basic flip phone from early 2005. I currently have a feature phone unlimited data plan on my account, that worked fine on 3G on my old phone, but I can only get EDGE on this phone. When I go on the AT&T website and look at my account, it shows the device as unknown. Could it be since the device is unknown they restrict the data to EDGE only?
I happen to have an old 3G flip phone. I can be sure it will never be used again since the pins on the SIM slot broke. If I were to change the IMEI number to that phone's IMEI number, is it possible it would allow 3G?
You can't change your phones imie number its illegal and would get you into serious trouble

I have one which had two legal printed imeis which worked until I pressed factory reset which wiped them. How can I put them back.
There is nothing illegal in this as I have proof they are the phones numbers

You will find no info here on editing the imei as this is illegal and not to be talked about here.

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.

I have been using a htc inspire that I totally love and now I am forced to use a iphone 3gs by my company. The iphone came with it's own simcard and it was activiated using my existing number. Now my number is tied to the iphone's imei number and I guess the iphone simcard and if I try to put the iphone simcard into my inspire it doesn't work (no service). Is there a way to get around this? They both use the same activesync technology, so it's not like one is more secure over other
Is it carrier-locked? It most likely is, if you don't get any signal. I've never heard of the IMEI being tied to a simcard/number.
Yes it seems to be carrier locked. I called the carrier and they said they would need to do a imei swap i.e. associate imei of my android device with the iphone simcard. Is there a way around this? I hate this iphone
Okay Developers & Non-Developers, Simple Explanation to my Problem.
1)Sprint manufactures a phone with Contract lasting for 1 year. This is a CDMA phone. John buys this phone in USA.
2)After contract is over, John's Friend - Jill Takes his phone to India, Goes to Reliance CDMA Gallery and Unlocks this phone, She gets a New phone Number.
3)Now Jill is happily using the phone. Note that, She has RELIANCE network and her Phone number is "INSERTED" in the phone as this phone doesn't have a SIM Card Slot.
4)Jill deciedes to sell this phone to me. She ERASES everything including her number which was in the phone and sells it to me.
5)I already have a CDMA Reliance Phone. All i have to do is go to Reliance CDMA Gallery and "INSERT" my number in this phone.
6)When I go there, Reliance girl says "The person who used this phone before, we need her number in this". I say"But she deleted this number". She says"Get her number first or the phone is useless".
7)She does not answer her call.
8)My question- Is there anyway i can I) INSERT my Number into the phone?
(II)o something to the hardware so that I can Directly insert my CDMA Reliance SIM?
Awaiting Reply. Panic-Stricken! :crying:
You'd have to flash it yourself through CDMA WS, DFS, or qpst. Google them, but I think Dfs and qpst have free versions.. Make a backup of all the settings first through whichever flashing to you use though!

Alright, so using DFS or QPST i have to FLASH another ROM in my phone? Or REPAIR stuff within it?
First off, I'm not a professional or very good at this
so be careful, in fact, if I were you, I'd have someone else flash the phone for me. Anyways, you're not flashing a ROM, you're flashing your number and and all the other stuff that goes with it to the phone. I'd use a donor cheap junk phone that's already flashed to your line, and copy the settings from there. Then experiment with the settings to get data/MMS working

I've never had a smart phone. I've always just used a little cheap "texting" phone with a regular sized SIM card from AT&T.
I want my first smartphone and I've decided that I like the Nexus 5 because I use to own a Nexus 7 Tablet, in which I assume are similar in some ways. I live in CA, USA
My question is whether I would have to get a new SIM card from AT&T. Right now I have a family plan with no Data services. Just an unlimited texting service and minutes. I'm always around Wi--Fi so I feel that I won't ever need any kind of data plan (2g,3g,4g,LTE). Because the Nexus 5 is unlocked, I was questioning whether AT&T would force me to purchase a Data Plan for this phone. Is there any way around it as of right now? Do I need to show them my phone to get a new SIM card (if needed?
Edit: I was doing some research and found this thread http://forum.xda-developers.com/showthread.php?t=2507422 , but it wasn't much of help since the phone wasn't out at the time.
Does this work?
You have two choices for the SIM card.
- cut it down to Micro SIM size
- Get a new Micro SIM card from AT&T
Here is the problem that you'll most likely run in to.
When you put that SIM card in your Nexus 5 the good folks at ATT will detect it's a smartphone and require you to get a data plan for the phone.
nexus 4 was detected by at&t
nexus 5 will be as well, especially since it'll be sold by t-mobile (t-mobile phones are detected on at&t, the two carriers probably share IMEI lists)
some people have luck by first adding a data block (no MMS though) on the line while using a dumbphone, then switching SIMs (but you'll need to keep that data block)

Aw man, and there is no way to change this so called IMEI (I think that's what it's called correct?).

Is this what changing a phone's IMEI is? There isn't some kind of rooting you can do to change the phones IMEI number into something else so that they can't detect it?

Ok with that being said, I will not discuss on how to change an IMEI, but I would like more information about this.
Would changing the IMEI from Phone A (Nexus 5 Legally purchased) to Phone B (Samsung Texting Phone Legally Purchased) be illegal?

I don't believe it is but some are quick to point to laws that don't exist.
Doesn't really matter at this point as it is not possible to change your imei on the n5.

That's true.
Is there an alternative way to use the Nexus 5 without having a data plan then? What about prepaid from AT&T?

as I said, try the "put data block on line before switching sim to nexus 5, keep data off on the nexus 5"...
if it doesn't work, then move away from att
Agree with the above comment. A friend of mine did the same thing with his Nexus 4 and he still hasn't been caught by Att and he got the phone since last March. So call Att from your dumbphone and cancel data access.
Could you let us know how it goes?
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.
