Hi @tjackson,
If your lockscreen shows Public Mobile but calls/text/data all fail, it’s usually one of these: (1) a stuck/partial registration on the network, (2) the phone holding old settings, or (3) your line needs a quick re‑provision by support. Try this order:
1) Fast radio refresh
Toggle Airplane mode ON for 60 seconds → OFF.
Power off the phone.
Remove the SIM, wait 30–60 sec, re‑insert, and boot back up fully (enter lock PIN so radios come up).
Settings ▸ Connections ▸ Mobile networks
Network mode: 5G/LTE/3G/2G (Auto). If already on that, briefly switch to LTE/3G/2G (Auto), wait 2 min, then back to Auto.
Network operators: set to Automatic.
2) Make sure VoLTE is enabled (critical after 3G shutdowns)
Settings ▸ Connections ▸ Mobile networks ▸ VoLTE calls (SIM 1) = ON.
If VoLTE is OFF or missing, voice/SMS can fail even while you “show” connected. (Support can also verify VoLTE is provisioned on your line/IMEI.)
3) Reset APN/IMS bits (clears old carrier values)
Settings ▸ Connections ▸ Mobile networks ▸ Access Point Names (APN)
Tap ⋮ ▸ Reset to default so the SIM loads PM/TELUS automatically.
If APN is blank after reset, add the official Public Mobile APN for your model (we can post the exact fields if needed).
Then go to Settings ▸ General management ▸ Reset ▸ Reset network settings (this will also reset Wi‑Fi/Bluetooth) and reboot.
Note: MMS requires Mobile data = ON, even on Wi‑Fi.
4) Isolate phone vs. line
Put your PM SIM in another unlocked phone.
If possible, try a different SIM in your A52 to confirm the radio is fine.
5) Check account status (quick sanity)
In My Account ▸ Overview confirm Subscription: Active and no payment suspension. If it shows ended/suspended, add a voucher and resume.
6) When to contact a CS_Agent
If after the steps above there’s still no voice/SMS/data:
Ask a CS_Agent to re-provision the line (refresh on HLR/HSS), enable VoLTE/Wi‑Fi Calling, and check IMS registration on your IMEI.
Mention you see Public Mobile on the screen but cannot place/receive calls or use data.
Samsung devices can hang onto old profiles or fail to register IMS/VoLTE correctly. A reset of APN + network settings and a fresh attach usually fixes it; otherwise a quick back‑end refresh does.
Post back your A52 exact model (A52 5G or 4G) + Android version, and we can give the precise APN fields/menu taps for your variant. You’ll be back up shortly.
Bonus tip for Samsung A‑series (A52 included): try LTE‑only for stabilityIn some areas we’ve seen A‑series phones behave poorly on 5G/NR—data drops and IMS (the bit that carries VoLTE/SMS/MMS) won’t register cleanly even though the lock screen still shows Public Mobile. As a quick stability test:
Samsung A52 path:
Settings ▸ Connections ▸ Mobile networks ▸ Network mode → select LTE/3G/2G (auto) (i.e., disable 5G temporarily).
Keep VoLTE calls = ON.
Use the phone for 24–48 hours.
If voice/SMS/data are solid on LTE, it’s likely a local 5G interop/coverage quirk. You can share your postal code + time of failures with a CS_Agent and ask them to flag it to the network team. They may recommend staying on LTE until a 5G fix/optimization rolls out for that area.
This doesn’t turn off high‑speed data—LTE on PM/TELUS is fast and often more consistent. If issues persist even on LTE, proceed with the re‑provision/APN steps above and have support rebuild the line.
All the best!
