I can't connect to my operator network, there is not signal, I'm able to do call with wifi, but out in the street I don't have connection or data. Is any part that I can replace?
Is this a good question?

If Wi-Fi calling works but you have no signal outside, the issue is usually SIM, settings, or antenna — not something you can easily replace yourself.
Try this first:
Turn Airplane mode ON for 30 seconds, then OFF.
Restart the phone.
Remove and reinsert the SIM card (clean it gently).
Test your SIM in another phone. If it also has no signal, contact your carrier for a SIM replacement.
Reset Network Settings (this won’t delete photos/apps).
If the SIM works in another phone, your device may have a faulty antenna module or baseband issue. That requires professional repair — internal antenna parts aren’t easy DIY fixes.

WiFi calling worked but zero signal outside, and it turned out not to be a “replaceable part.” First check SIM (try it in another phone) and reset network settings; if that doesn’t fix it, it’s usually a carrier issue or a damaged antenna/modem, which isn’t really worth repairing. I’d rule out SIM/carrier before thinking hardware.
