@joseph_1979 thanks, what do you mean by 'apn' ?

My sim card has been blocked by my provider so I can't access my camera. When I insert a new sim card, will my reolink app work without needing to change any settings, or will I need to change something?

@joseph_1979 Hi, no I'm not able to connect to my camera by any method now, because Lebara has stopped my sim card from working.

Can anyone recommend a sim card to use abroad (Bulgaria) which will work in the UK? I've been using Lebara sim but they've cut me off due to 'fair usage' policy because most of my data allowance is used abroad. I can't now access my camera in Bulgaria from home in the UK.

Thanks...
