Great reminder about keeping devices in top shape! Just like organizing your setup or enjoying a relaxing coloring sheet session, maintaining a valid IMEI ensures smooth 4G performance.

It sounds like your device’s IMEI isn’t configured for 4G compatibility. You may need to contact your carrier or visit a certified service center to correct it. Proper block management of network settings and firmware updates can also help ensure your phone connects to the right frequencies.

I'm in France and my phone doesn’t get 4G  the IMEI shows it's only compatible with 3G bands.
My carrier sees it as a 3G device, so no 4G connection at all.
Tried swapping SIMs, still stuck on 3G even Null's Brawl lags badly.
Is there any fix or workaround to get 4G working on this model?

Great explanation! Just like an invalid IMEI can disrupt 4G connectivity if not properly registered, medical professionals rely on toolsmedical professionals rely on tools like the TI-RADS calculator to ensure accurate assessment of thyroid nodules. Both show how having reliable, correctly configured tools—whether in technology or healthcare—makes a huge difference in outcomes.
