Set up roaming
So I have a smarty sim in and old 3 mobil 4g Mifi device. It works perfectly at home but not at all here in Malta. The advice from smarty is all based on using a phone. Is there an easy trick to get it to work without having to move the sim to my phone, twiddle and move it back. I really wanted to be able to use it and I can’t. My current contracted provider charges me a daily fee for roaming. Thanks
