Restoring SMARTY Service on Samsung
Turn Airplane Mode on, wait 15 seconds, then turn it off. This forces your Samsung to drop and re-register on the SMARTY network from scratch.
Power off your Samsung. Remove the SIM tray, take the SIM out, check the gold contacts for dirt or damage, then reinsert firmly. Power on and wait 2 minutes.
A full restart clears radio firmware errors that can cause No Service. Hold power and tap Restart. Allow 2 minutes for SMARTY network registration to complete.
Visit SMARTY's coverage checker or network status page to confirm there is no outage at your location. During outages, No Service affects whole areas simultaneously.
Go to Settings → Mobile Network → Network Operators → Search manually. Select SMARTY from the list. This forces re-registration when auto-search fails.
An unpaid bill, spending cap, or suspended account shows as No Service on your Samsung. Call smarty.co.uk live chat from another phone or check the SMARTY app to confirm account status.
As a final step before requesting a SIM replacement, go to Settings → General Management → Reset → Reset Network Settings. After reset, wait 5 minutes for SMARTY to re-register your device on the network.

Frequently Asked Questions
Why does my Samsung say No Service on SMARTY?
No Service means your Samsung cannot register on any SMARTY network cell. Common causes are an improperly seated SIM, a failed SIM card, an account suspension, or being outside SMARTY coverage. Toggle Airplane Mode and reseat the SIM as first steps.
How do I check SMARTY network coverage?
Visit SMARTY's website and use the coverage checker — enter your postcode to see whether SMARTY 4G or 5G coverage exists at your location. If SMARTY shows no coverage in your area, No Service is expected.
Can a software update cause No Service on SMARTY?
Yes — some firmware updates reset network preferences, remove APN profiles, or change preferred network mode settings. After any update, go to your network settings and verify SMARTY is selected as the preferred network with the correct APN.
