SMARTY SIM in Doro 6520

[Thorste_1398745]

Hi. I have put my SMARTY Sim card into a Doro 6520 flip phone (using a Nano to Micro Sim adapter). The phone won't recognise the SIM at all; red cross in the top left and SOS call only in the display. I believe the Doro 6520 is a 3G phone. Any tips gratefully received. Thank you 😊

One option: The Doro 6520 only works with 2G 3G SIMs / Networks. SMARTY is 4G. So it won't work. Might that be the answer?

@Thorste_1398745  As 3G has been turned off, the phone has no network to connect to.
