https://community.bt.com/t5/BT-Mobile/Doro-phone-can-sent-text-but-don-t-arrive/m-p/2470419#M25597 <P>Recently my mother's doro phone has an issue. The phone can received texts but when she sends a text the phone said it has been sent but it never arrived. She has a unlimited text plan. I checked the SMS Centre number, seems correct and I put my SIM in her phone and it's working. So I bought another Doro phone for her but the new one has the same problem. Do you think it could be the SIM itself?&nbsp;</P><P>Any ideas will be very helpful, thanks.</P> Sat, 12 Sep 2026 15:43:04 GMT Tonymay 2026-09-12T15:43:04Z https://community.bt.com/t5/BT-Mobile/Doro-phone-can-sent-text-but-don-t-arrive/m-p/2470419#M25597 <P>Recently my mother's doro phone has an issue.
