Problems since I upgraded my tariff

[Steven1927]

Since I upgraded my SIM only tariff yesterday I am unable to make or receive calls and I have no mobile data.

Any idea what might have gone wrong?

If you ordered a new sim then your current sim will have been automatically disconnected

Unfortunately you will need to wait for your new sim to arrive
