Try these in order:
- Switch networks: turn off automatic network selection and manually pick a different local carrier — this helps most often
- Toggle Airplane Mode or restart your phone
- Move locations: basements, deep indoors, mountains, and high floors all weaken reception
- Consider the time of day: networks get congested in the evening and at busy tourist spots
- Check your data balance: on unlimited plans, speeds are reduced after the high-speed allowance is used
- Check 4G/5G settings: where 5G coverage is patchy, forcing 4G can be more stable
