I'm based in South Africa and keep a giffgaff SIM for when I come back to the UK, so I can top it up and use it for the couple of weeks I'm down here. Before flying down the other day, I grabbed my SIM, topped it up and got on the flight.
However, since I got here and inserted the SIM, my phone has failed to pick up the network at all. My thought is that perhaps I've inserted the wrong SIM (I probably have more than one), but giffgaff won't let me swap the goodybag to the SIM I *do* have (I receive the message "This SIM can't be activated at the moment. Please visit the help section".
So what are my options? Do I have to pick up a new giffgaff SIM to transfer my goodybag to?
* Bought my phone (Moto G5) through giffgaff so network, hardware etc. should be compatible.
* EDIT 1: Thought my phone settings might be out of whack. Went into Settings > Wireless & Networks > Mobile network settings > Network operators and tried to choose giffgaff as my mobile operator, but received the message "Your SIM card does not allow a connection to this network".
