I received a device 2 days ago, followed all instructions, tried to activate SIM card, but it doesn’t work. I have already tried to reconnect and other recommendations, but nothing helps:(
My contract number is xy
Please advise what should I do to activate the internet connection? How can I change the device?
Regards,
Anna
