Frequent changing of sim is not advisable... try to bring cellphone to a cellphone repair shop and ask them to format it. the software may be corrupted. there are also codes on how to format cellphone using codes, try *3 and call button. (caution all the data on your fone will be lost once you format it)

No network


Hey. I think this is a general problem with the K770i. I have one also and it will turn itself off and then back on everytime there is a bad signal when the phone is in 3G/GSM mode. Sadly The phone has a really bad antenna located in the bottom of the phone. You can try holding the phone upside down, (seriously it helps) or turn of 3G when you're in an area with poor signal.

I've solved this issue by going into the settings and switching the phone to ONLY GSM mode.
Goto "Settings"
"Connectivity"
"Mobile Networks"
"GSM/3G networks"
and then change it to GSM only.

And like magic your phone will stop turning itself off all the freaking time when there's a bad signal. :)

I entrd d wrng PIN code..n nw d phone iz askin fr d PUK code..n i dunno dat..wat shud i do to start up my fn nw??


Hi your only option is to call your phone service provider, no it doesn't come with the phone and the phone never has its own puk code becouse the puk code is about the sim card.

if you put in another sim card the phone will work just fine, its the simcard 3 times pin code wrong puk code enabled pin blocked, call service provider to get it and entery instructions.

Let me know if you need anything else.
Thanks,
Ekse

Network


try sim with other fone on same network, if prob cont. with other fone then contact your network.
If ok with other fone try selecting Menu>Settings>Press Navigation key right to find Connectivity>Scroll to Mobile networks>Select GSM/3G networks>Turn phone off>On.
If this doesn't work you will need to take your fone to a service center.
