I recently received a new SIM card from the telecommunications service provider I switched to (I kept my mobile number). This is what I have done so far:
- Went through the "activate SIM online" process
- Powered off my mobile
- Replaced SIM cards
- Started my mobile again
The mobile appears to have detected the new SIM alright (I can see the new provider's name) but it says "emergency calls only". I checked with the new provider's support and they said it may take up to an hour to get activated.
Now I am wondering, do I need to reboot my phone again before the new SIM can connect to the network, or are there other means of forcing the SIM to try to reconnect, such as
- switching mobile data off and on again,
- turning on flight-mode temporarily
- ...anything else?
