My phone will not come on

Save your pics, then re-format the card.

Well it depends...First take a sim card beside yours, one you know works, power phone off, insert sim, power phone up, wait 1 minute, if it still says no service, power down and take the sim card back out, reinstall the battery and power phone back on without sim installed. when the phone powers back on does it say "no sim" or "no service"? this is to see if the phone can decipher a sim being in the phone and it not having service. If it say no sim then the sim reader is working, if it says no service then the phone may not in-fact be able to tell the difference of having a sim card and having service. Regardless at this point it is not working and more than likely an internal electrical component has failed and more than likely it may be the radio communication circuit of the device, if you insist on keeping this device- find one with a cracked screen but working internal and dissemble it, and replace the main board in the unit- this will in turn change the esn' imie, the overall serial of the phone, so take note of the new phone serial number- only replace the main bored under the keypad,be careful because it is VERY easy to mistakenly damage the device and its components. I do not see an easier way than this to fix you issue besides taking it in for repair- the new phone does not have to be broken but must be operational for making and taking calls. save all of your information as it will be lost after transfer-more or less still on the old phone, if this is an unlocked device please return original carrier sim for testing, and if the unit does not accept sim card skip those steps, and be sure that the new phone does not have an esn lock--Good Luck

It the Phones says invalid Sim card means it locked to Network you need to unlock it from the network lock,you can get the network unlock code from here
Mobile-unlocker.com and unlock it from Network lock,then you can use with any GSM Network Sim card in the Phone.....You need to find the network and country it locked now and specify that to get the unlock code....

Hi it means the sim card you are using is not the same type the phone is locked to say your trying a orange network sim but the phone may be locked to vodafone.

if the sim card worked in the phone before then i would take the sim card out and give the contacts are rub then put it back in if it still dont work then this would suggest the sim card reader needs replacing, to get this done it will need taking to a phone shop.

if you are unsure what network the phone is locked to then you can take it into any phone shop and they will tell you for free what network its locked to.

let me know if you need further assistance ok

Hi if your phone is asking for the PUK code then what the phone is asking for is the security code for the sim card all you need to do is contact your service provider and give them your phone number they will then give you the 15digit code over the phone, they wont charge for this, but the code they give you will only work with the sim card thats asking for the code as every single sim made has its own unique unlocking code so write it down when they give it to you in case you ever need it in the futuere ok.

let me know how you get on or if you need further assistance ok

1.check the sim card if it is properly inserted.or try other sim card.
2.did you turn on your wifi?turn it on to have a signal from your network.
3.Is it unlock/openline already?
4.if the above mention is still not working its already a hardware problem.

the sim connector may be dirty and you can service it with methelated spirit by unscrewing it and allow it to dry before screwing it back, usualy with a soft mouth brush.

Kindly remove the sim card on the phone, there is a gold plated part on it right? kindly wipe it with a dry clean cloth then place it back in, let see if it will work.
