[Q] Using old device when not changing your IMEI with AT&T - Xperia Z3 Q&A, Help & Troubleshooting

All,
I have a general question, I use AT&T and got the Z3, now because AT&T does not sell the Z3 everyone told me not to change my IMEI with AT&T and keep the IMEI of my old HTC ONE M7 registered to my account with AT&T.
I was showing my friend my new phone and he asked what I was doing with my M7 and I told him I was planning on keeping it as a spare he asked me if I was willing to let him use it because he has a really old android phone and I said I need to research to see if there would be any negative effects.
So my question is if I let him use the phone will AT&T black list it because someone else is using the device when the IMEI is still registered to me?

[Q] My sensation wont recognize a specific simcard

First off, thank you for making a brilliant forum! Now that I dont get any further by searching for information I need som help from you guys.
Thing is: I have two sensations. Both are s-off, rooted, superCID and have the latest coindroid installed. Both are originally tmobile phones which were bought unlocked some while ago. They have both been used successfully in europe until now that im in the US.
For various reasons i have three simcards for these phones. And in one of them t-mobile doesnt seem to work at all. Neither before software modifications or after. The other phone with similar mods have no problems.
The other simcards are a norwegian one and another pay-as-you-go simcard which has been used since t-mobile doesnt work.
Since both phones are rooted and s-off I guess there is a setting somewhere. Where is this particular setting? Anybody that could come a newbie to the rescue?
Thanks!
no setting if phone dont ask for a unlock code or has been unlocked i am going to say bad/banned imi number call t-Mobile and ask them if your phone is black listed
The phone is blocked by tmobile it appears. Bought it off amazon nine months ago. The phone was sold as new and "unlocked" back then and w/o warranty, but not as stolen phone. Im angry right now.
Neither Tmobile or HTC are very helpful on the phone. Costumer service at Tmobile keeps failing to put me over to anyone who can help.
Any tips on how to proceed further? Showing up at one of their shops and stay there until someone is able to help?
Since the phone is without warranty its very tempting to do illegal stuff to it right now.

Like what free apps or fake call 911 lol not much you can do that's illegal
Only things you can do try att sim but may not work
resell on eBay for parts should get most of your money back or keep calling T-Mobile there the only ones who can if they will

[Q] Help please!

hello,i'm a new member here and this is my first post.Since my Galaxy ace broke i'm looking to find a new phone and i think i'm going with the desire s.I found this guy on ebay who sells his used desire s as faulty and claims it can't make or receive calls inside the u.k but after i asked him he said that it will work ok outside the u.k.Is that possible or is he lying.I really need some help on whether i should or shouldn't buy this phone.Thank you in advance and sorry for my english!
Well you can try to ask the guy where, more precisely, the problem comes from...
If it's a hardware issue (antenna?), i don't think the phone will be able to receive or send calls, neither in the UK, nor anywhere else. On the other hand, if it's a ROM / settings / software issue, it will probably be possible to fix it by installing a new ROM...
However if you need to change your phone, it's just my opinion but I'd rather go to a more recent model like the One S or One X... Not the same price though I agree.
Hope this helps
It could be the stolen phone and blocked by networks in the uk

try flashing the newest Radio Image.
Flashing a new radio won't do a thing if the phone is registered as lost or stolen, which is going to be the case unfortunately.
EDIT: If you get the IMEI number from him you can check it at http://www.checkmend.com/uk/ for a small fee.
If it is not getting signal in the UK only then it is because the phone has been lost/stolen and the owner has rang up the network and they have put a block on it
I would say its stolen and the original owner has reported it to there provider who has blocked the phone.
If you buy it you could be buying stolen goods, mrbishi is right get the IMEI number and check it.

[Q] S3 -GT-I9300 International version verification

Can some one help and tell me how I can find out where my Galaxy S3 gt-i9300 was manufactured and possibly what market the phone was meant to be used in. There are many of us on this forum that have had the sudden death issue and the first thing we are told is if your in the US we cant fix it but send it to the samsung service Center in the country you bought the phone in. HMMM easier said then done therefore the question is there a way to identify where the phone was originally meant to be used international,
I have seen a website that had a tool that you would add your serial number andEMEI number and it would tell you where the phone was from and carrier used etc but have not been able to find it again. Yah should learn to bookmark things ....

[Q] sim unlock & imei change

Hey everyone.
Thanks for taking the time to read this.
to be perfectly honest my dad has a att lg g3. A few months ago he switched to Verizon
due to a very large bill. He was considering selling the phone but was under the next program.
which means the device was Was not paid off. So I told him instead of selling it to someone then in a few month have the imei go bad Let me see if I can unlock the device and changer the imei, that way
the buyer isn't crewed over.
If any one can help me with these steps it would mean a lot.
Thanks!
Changing the IMEI is not allowed, and so is all discussion about it as well.
With that being said:
