Describe the failure
Write down whether calls, messages or data fail, where it happens and when it began. Record recent software, device or SIM changes. A repeatable description is more useful than saying the whole network is bad.
Check the official status
Look for a local incident or planned work. Compare one safe outdoor location and, if appropriate, a supported alternative handset. Do not repeatedly reset network settings or delete eSIM profiles without understanding the recovery route.
Consider voice compatibility
Mobile data working on 4G does not automatically establish that voice calling is configured correctly. Ask the provider about your exact handset and its supported calling features, especially after network-generation changes.
Keep the next step clear
Ask for a fault reference, the action being taken and how to follow up. A new data allowance will not fix every radio, device or provisioning issue. Urgent lost-phone or account-security matters belong directly with the provider.
Keep the next step official
General information cannot confirm personal account conditions. Read your provider’s current documents and use its official channels before making a change.
Your next step remains your decision.
