Hi ​@molliegarrity.

Thank you for sharing.I’m sorry your service has been dropping out and running slowly since you got back from travelling.

Please check the coverage in your area at https://www.idmobile.co.uk/help-and-advice/coverage, as this will show whether there are any known issues where you are.

If coverage looks fine, please try a network reset, as your phone may still be holding settings from the networks you used abroad.

For an Android device:

Open Settings and tap General management.
Tap Reset.
Tap Reset network settings.

For an iPhone:

Go to Settings > Messages and turn off iMessage.
Go to Settings > General > Reset.
Tap Reset Network Settings.
Once your iPhone has restarted, go to Settings > Messages and turn iMessage back on. This will recognise your SIM and verify it.

Please note that a network reset will also remove your saved Wi-Fi passwords, so you’ll need to reconnect to your Wi-Fi networks afterwards.

Thanks,

Marquerita
