Hi @dawn201616 , welcome to the community. Sorry to hear you're having issues with one of your lines. A few questions for you, is your Samsung s8 up to date with system and app updates? Have you tried your sim card in any other phone to see if it improves? If I recall correctly the S8 is no longer supported by Samsung for any further updates so it may be possible that the device isn't up to date with any changes to carrier upgrades. See if the card works better in another device, or not and if it does it could be the device. If it remains the same, then further investigation is required through fido tech support. You can reach a customer service representative by calling them at *611 from your phone. Hope this helps a bit, have a good evening,  cheers OL
