Sim2 invalid problem solution


A mobile will display a message as "Invalid SIM" if it is locked to a particular network. Hence a sim SIM card other than the compatible one is inserted, immediately it prompts Invalid SIM or Wrong SIM. To use other networks you first need to unlock the mobile. To unlock your mobile you can use the unlock code. Unlock code can be got from TheUnlockSpot.com once all your mobile information is submitted.

Hello i have china phone i9++i model in security set up sim2 it was asking puk2 pl send the puk2


Hi,

The easiest way to get the PUK code is to call your service provider, such as T-Mobile or Verizon. They need to verify your cell phone number and your IMEI number and they will provide you with the PUK code.

Hope this helps,
Joe

Most of these I68 SCIPHONES have the same imei number, and alot of these are being blocked. So dont be suprised if you wake up one morning and it doesnt work.
