I have a XV6900 in China, I have a strange question. the ESN
can change automatically. The ESN is invalid when sim card is inserted.
the ESN will never change on your phone. So if it wont work the it has been FLAGGED for LOST or STOLEN

Hello all;
I was wondering if there is a way to clone my esn from my old PPC6700 so I can use a Sprint PPC6800 on the Telus network.
6800 ESN Change
Can somebody give the solution for changing the ESN of Mogul.
Thanks in advance
just got my lg c900 today from ebay, and when i insert my att sim card, it says "invalid sim card"...
But I have been using this sim card on other devices, like nokia 2710 and my touch 3g and they work fine!!
So i tried someone else's sim card(Att), it works too!!!
What should i do.....
You need to unlock the phone to use with other carrier. There are a lot of unlocking services that can help you to unlock it.
Aha!
I had the exact same 'problem' and freakou... er... reaction.
You have to activate a plan on the SIM card. Only then will it stop giving you the INVALID SIM message at startup.

Jesus! Is there no other way out? I didn't buy it from AT&T and don't want to pay for the data plan....
can i just don't make a data plan but just enable the data connection?
If you want to use the phone or Data (excluding Wifi) functions of the phone, you'll need to have some sort of plan or prepaid account associated with the SIM card.
It doesn't mean you have to pay the 'Smartphone' package that AT&T offers (forces) when you get the phone on a contract. You don't even need to have a plan at all! You just need to activate an account online.
Thanks, but actually this is not my contract phone. I bought it from someone else. In my current contract my device is a basic phone, but I enable the data connection function(pay per usage).
But it's still not working...what a wp7....
what do you mean by activating an account online? I already got my account.
Well, on Telus, you just had to activate a phone by entering the SIM number (it's on the little card you received with the SIM or sometimes on the SIM itself) in the 'Activate your Phone' wizard.
Problem fixed!!!!
I call the ATT customer service and they update my sim card information. now it works!!!
Excellent to hear! I'm glad your problem got fixed
Hi there guys I have a LG C900 that is an ATT phone. I inserted a non att sim card and have PUK locked the phone. I tried calling ATT and asking for PUK code which they were able to generate but the code did not work. I also have the unlock code for this phone but whenever a non att sim card is inserted it asks for a PUK code. Does anyone know what I can do?
Not sure ATT could help, where is the sim from and what are you trying to do with it?
Is the PUK code related to the phone brand or model?
The PUK code has nothing to do with your mobile phone’s brand (i.e. Nokia, Motorola, Samsung, Nextel, Sony-Ericsson, LG) or model. The PUK is only tied to the SIM card.
What happens if I lost or forgot my PUK code?
If you are a postpaid user (Globe, Smart, Sun Cellular, Verizon, T-Mobile, Orange or AT&T), your cell provider may be able to provide you with your PUK code. Just call them up, authenticate your identity by answering some questions and they will give you the PUK for your SIM card. This is easy because the telco can verify you as the owner of the SIM card or the mobile number.
PUK Code was generated with an over seas sim card. If I put ATT sim card in the device it does not ask for PUK Code. But also if I put a T-Mobile Sim card it asks for PUK.
I have the same problem as you have you solved?
same problem here, any solution !
hi!
i recently bought an omnia 7 on ebay, t-mobile locked.
due to i have a vodafon contract, i unlocked it online, with imei unlock.
now the phone accepts my sim card, but i keep getting "no service".
today i bought a t-mobile sim card, just to try, and it is the same.
when i am changing sim cards, the network profile app changes the settings.
i flashed another rom, found here (jj6 uk), i updated to 7720, nothing helps.
i guess it isnt the sim card reader, cause the network profile app recognises any sim card.
is there an antenna problem or just some software thing?
can i fix the antenna by myself, if it is broken or sthing?...
i fall in love with this phone, i dont want to get rid of it...
any suggestions appreciated.

thats the way it is for now- I do not condone changing esn numbers but I have confirmed I have repaired a few that lost signal do to esn changes- currently is no way to modify esn and retain any signal on the sprint model and on the us cellular it will work but without 3g

well thanks ...imma use my s5 like an ipod lol
please if anyother knows how to fix my problem
Any solution so far?
Were you guys able to get this problem solved?
Right now I am in the same situation.. if I change ESN/MEID I lose signal and I can't seem to change the IMEI at all .. DFS shows that it changes but after restart, only ESN/MEID is changed, IMEI always stays the same. I beleive that is the problem because ESN/MEID and IMEI aren't matching somewhere in the code.
Please do let me know if there is anyway to get the signal back.
Thanks!
Hi I am also looking for the same solution to this issue. Any luck?
If anyone have a solution please help!
What things have you guys tried? Only things I can think of right now is messing with IMEI repair and trying out different PRLs.

I am having the same issue. Im positive if we could change the prl it would bring the signal back.
Got 3G no voice
Hi I am in the same situation but i can get 3g with original esn but i must change esn to get voice since i'm outside usa
the answer is the Baseband.
I have a Sprint Note 3 & every time I've tried to update past the MJ4 Baseband, I lose signal.
I Flashed it to Boost & I've also tried manually flashing the PRL, still a no go.
my advice is to try downgrading the Baseband.
