Hi, I came back from holidays yesterday morning and since that I have no service, I turn my phone on and off several times, I remove the SIM and put it again.. but does not work.

I cannot call and nobody can call me, I have no internet and I cannot send sms neither receive them, it says only emergency calls.



My phone is a Samsung GT i8262 Galaxy core dual SIM.



I travelled many times before and just when I went out of the plane my phone was properly working(calling, internet, sms). What can I do?



Thanks.

Anna.
