Common network issues & fixes
🔴 No service or network registration failed after landing
✅ Confirm data roaming is enabled, toggle airplane mode to reconnect, or manually select the underlying operator shown on the page.
🔴 Slow speed or video buffering
✅ Check if high-speed data threshold is exceeded, then try switching between 4G/5G or changing location.
🔴 Hotspot not working or second device cannot connect
✅ Choose a plan with hotspot support first. If already purchased, reset personal hotspot and check if APN is automatically configured.
