Signal Lost at Home?

Any suggestions please about how to check/boost signal? I moved from Samsung S3 to Fairphone and mobile is my only phone at home … that used to work fine, but Fairphone keeps leaving me with no signal at home - or people ring and it’s right next to me/full volume and nothing rings? Any obvious tricks (I am social media rather than tech savvy!)

What is the name of your provider?

Three. I haven’t changed my SIM card, and have been using the Fairphone (3?) months - and noticeably worse …

About the ringtone: Androids Audio Settings can be downright confusing. Check out: The ringtone doesn't ring anymore

@drbexl are you still having problems?
