No connection

[Dmitry]

Hi i just recently moved to o2 from another network.
And hust from the start I have no connection and no wifi. There is just no network connection anytime.
When I choose the o2 network it just says the sim does not support this.
Please help!

@Dmitry Did you port your number from your original network? Did O2 send you a new sim card?

Your WiFi connection would have nothing to do with O2.

Joining O2?

If you’re switching to O2 from another network, we’ll need your PAC or STAC code.

Once you’ve given us your code, you’ll switch to our network within one working day (Monday-Friday, 9am-5pm, excluding bank holidays). If we receive your code after 5pm, you’ll switch within two working days. When you lose service on your old network, just swap your old sim card for your new O2 one and turn your phone on.
