If you're worried about the missing Personal Hotspot, don't fret too much. Apple has separated the APN settings, no longer shared with 3G networks as before. You can reset it as follows to make it reappear:
The APN for the personal access point has parameters similar to the 3G APN. Different network providers may have different settings:
Step 1: Go to Settings > Mobile
Step 2: Proceed to Mobile Data Network > scroll down, and you'll find the 'Personal Hotspot' option
Step 3: Enter the APN (Access Point Name), Username, and Password corresponding to your network (details below)
Step 4: After entering the information, the 'Personal Hotspot' option will appear in the Mobile section.
Details for each network:
- VinaPhone: APN: m3-world, Username: mms, Password: mms
- Mobifone: APN: m-wap, Username: mms, Password: mms
- Viettel: APN: v-internet, Username: (leave blank), Password: (leave blank)
- VietnaMobile: APN: Internet, Username: (leave blank), Password: (leave blank)
