No, that's a GSM phone, and sprint/nextel is not a GSM service, sorry. sprint is their own version of PCS, and nextel uses this strange beast called "iden", though I believe it's being phased out now that sprint gobbled them up.
in the US, the primary GSM carriers are Tmobile and ATT.

Want to unlock phone samsungL770

Hi you can unlock your Samsung L770 using the unlock code. you can get the unlock code from this site at reliable cost.

Do not enter any wrong unlock codes on your Samsung L770 mobile phones. If you enter over a certain amount of wrong unlock codes on your Samsung L770 mobile phone, your phone may get hard locked and sometimes become unusable.Method 1:

1 - Switch ON your Samsung L770 with a NOT ACCEPTED SIM Card.
2 - Samsung L770 will ask for "Password".
3 - Enter the Unlock Code.

OR (if the Samsung L770 shows "Insert Correct SIM Card")

Method 2:

1 - Switch ON your Samsung L770 with a NOT ACCEPTED SIM Card.
2 - Don't bother about what's being displayed on your Samsung L770.
3 - Compose : #0111*CODE#.

NOT ACCEPTED: We mean, to use a sim card from a network other than the network your Samsung L770 is locked to.
CODE: Its the unique Unlock Code for your Samsung L770.

If method 2 does not work, you can try method 2 again but this time without any SIM card on your Samsung L770.

I have an cect i9 dual sim phone i have two sims both register on phone but only one dials out the other shows network failure tried switching position of sims but stil only one works

Which sim slots works? Or is it only one sim card that works? If it's only the sim card, check with your wireless provider, it could a conflict between the phones technology and the band that your service provider use. If it's the sims slot then try going to sim profile and enable both sim, for starter. You don't state whether your phone is a quadband or a triband.

I68+ TOUCH SCREEN emergency calls only

No it doesn't mean that is not unlocked. It only means that you have a Sim card that uses a frequency that most probably your i68+ don't have. Some of those phone are sold as quadband, but are truly triband. If you phone company uses 850mhz. and your phone is a triband then you won't be able to use your sim card with the phone. Also make sure that both sim card slots are enable, go to the sim card profile and tap it, here you will have 4 options, tap on dual sim. To enable all bands you will have to go to engineer mode and that is a risky move if you don't know what you are doing.
Engineer mode: *#3646633# then go to Network set up, choose band select, and make sure that auto is checked. Stay away from HIGH SPEED SIM, if you tap it you will brick your phone and it will be useless.

Lg kf700 wont accept any sim cards,


it sounds weird that it worked before with same sim card. Generally USIM locked message means phone is locked to network and you need to unlock it with network unlock code to remove USIM locked and use phone on different network.

Wats the munber for the puk code lg i am on 02

PUK code, (personal unlocking key).

This is SIM card related / specific. If you take the SIM card out of the phone, the phone will work with another sim card.

The puk comes up when the pin code has been entered wrong 3 times. To get the puk code for your sim card, you have to call the service provider of that sim card. They are the only ones who can provide you with the right puk code for that sim card.

The puk code may also have came with the documentation of the sim card, if its a prepaid card the Puk code comes on the documents or on the box of the product.

if your unable to obtain the puk code, get a new SIM card.

Also entering the puk code wrong too many times will eventually ruin the sim card forcing you to buy or contact your service provider for a new sim card.

There are no PUK code calculators or anything that we can do about it, you can buy premium assistance and you will get this same response. There is no other solution.

You have to contact the phone service provider of that sim card or replace the SIM card.

My phone is block and i dont no my puk code

PUK means "personal unlocking key" .

The PUK code is asked if you enter a wrong pin 3 times.

You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.

In your case you need to contact your SIM card provider technical support to unlock the SIM.

The PIN and PUK are related to the SIM card, not to the phone.

If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.

Lg shine ke970

I'm glad that there are other people out there was having this problem. I spent about a total of 48 hours talking to the AT&T customer service to see what the hell the problem was with my phone not picking up service. The couldn't really help me. So...

I did some research and found that T-Mobile is the largest GSM provider for Triband and Quadband phones. I have the Lg KE970 and since it's a triband phone, I was really hoping that t-mobile would give me great service with it. NOW...

The next thing that I did was contacted T-Mobile to see if the coverage was good in my area (Lubbock, Texas) and they said it was excellent. So then I went from there.

The next thing that I did was went to wal-mart to pick a up a free sim card and as soon as I popped it it, BAM!!!, 5 bars. So right then and there, I called up T-Mobile to set up an account.

So yeah, if you didn't get any of that, just switch to T-Mobile and import your phone number there. PLUS, they have a limited time promotional offer where you get 1000 anytime minutes and free nights and weekend minutes for only $39.99.

SO switch to T-Mobile and get that plan. It's worth it and no matter what, you will still be on that plan. :-)

I hope that helped you guys!

If the SIM card comes from a country that does NOT have a roaming agreement with the country where you are trying to use it, it won't work.
Also you may have to select a network manually. In some countries for whatever reasons Auto select won't work.

If you switch 'Cell Info Display' on your phone to 'on' it will show you when you change from one network to another.

I'm not sure about t-mobile in the US of A.
