Invalid sim means the sim card may no longer be active , faulty or the device is network locked , cheapest option is replace the card if still not functioning the issue is with the device , giffgaff will not use the same APN as O2 , that may have to be manually input
Hi. If your SIM is under postpaid plan, telcos usually activate the SIM within 24hours. If your SIM is prepaid, you may have to call the vendor and ask for replacement. SIM with "registration unsuccessful or rejected" is either not yet activated or expired. If you get "Invalid SIM" that means either the phone is locked to other network or the SIM is not active. Since your phone and SIM are new, it is more likely that your SIM is not yet activated. Please call your vendor if SIM is still rejected after 24hr period. Thanks.
when u press *#06# your phone shows imei and imeisv no. , so actually only one sim has a valid imi no. so u have to to a valid imei installation shop n have to get a valid imei installed
i think the phone use other provider than your sim card if you put orginal sim card from provider in it the sim card wil be acces unlocking the phone you can acces all providers you have contact old provider they wil give you unlock
codes after one year for free , you have to give them your imei number
you see it under battery or by pressing *#06# and also the old phone
number they wil also handel it with email
This may because your cellular phone cannot recognize the sim card,may be the sim card doesn't insert deeply or the card slot is loosening,you can
try to insert it deeper and tighten the slot.
i have the same problem i keep on putting my sims in (one tesco sim & one voda phone sim) and it said the same thing invalid sim. the sim regestars for about 2 seconds then it either says invalid sim or emergancey calls. whats a matter with it should i send it back.kjr2502
Ok, this sounds f**king stupid, but, try this
-Dial *#000#
-change the date to one in the past
-switch phone off then on
-change the date back to present
-switch phone off then on
This worked for me.... don't ask me why i even tried this
