I am also having trouble with the new SIM. My 91 year old grandmother has an old Nokia phone and when the new SIM is inserted it comes up with an error message saying SIM not valid. Please can you advise ASAP as I do not want her to be without a phone. I am finding it impossible to get through to speak to anyone.
No1 else has a virgin handset unfortunately. Plus none of us have a phone that is old enough to use the larger size SIM in. If I purchase the Nokia 105 (2019) will the SIM work in that phone? The phone needs to be as simple as possible and that is the closest match I can find.
