Why do people sell no good stuff must be a mug
Thought was to good to be true , have followed the instructions in every possible way deciphering very possible alternative but still do no work . IED 3 g , 4 g , 5 g SIM cards but still no joy . You only get 1 message back “ config ok “ but nothing else . Honestly beggars belief I have been had over 🙈

Not bad
Does the job. Cannot complain at all for the price. I think people are experiencing issues due to the SIM. I read elsewhere it’s not very compatible with some like O2. But others like EE are much better. I got a lebara one off Amazon and it works just fine. Only issue is it switches off every 1-2 mins and becomes user busy. You just have to keep calling it back. If you have the patience for that is defo does the job and is worth the money
