@marionmumford Fingers crossed the replacement SIM should help make a difference here.
When you speak with our tech team about any network issues, our key aim is to try and identify if the issues are down to the network, the SIM, or the device itself.
There's no obligation to send it away then and there, so you can spend a bit more time testing the connection with the new SIM and trying to identify any patterns.
I would make sure to request a password on the account when you provide ID too, as this can be used as another layer of security should you need to call.
