Transfer SIM to new 4G Doro 6820, need to keep all texts on old 3G Doro 6620

[EESandwich]

Hello all,

Hope you can help.

My elderly mother has an old Doro 6620 Unlocked 3G phone, which now struggles to find a 2G signal/function now that 3G coverage has been turned off in our village. Due to this we have purchased a Doro 6820 Unlocked 4G phone.

For personal reasons, my mum wants to keep all texts/photos/voicemails to remain on the Doro 6620 phone - the text messages are stored on the phone, photo's on memory card. 

If I take the EE SIM out of her old 3G Doro 6620 and put the SIM into her new 4G Doro 6820 - will all her text messages remain on her old 3G Doro 6620, even though it will no longer have any sim in it. Will the texts then stay on the 3G Doro 6620 phone forever?

I cannot take any risks in losing any of the texts/photos/voicemails from the old 3G Doro 6620 so I need to be 100% sure before I try anything.

Many thanks

He has texts from his brother he's not long lost, can you confirm that you were able to keep/view the messages in anyway?

Any texts on his phone will stay there. That has nowt to do with the network signal.
