SAFE CHECKS IN ORDER

What can you try?

Try these safe, user-level checks in order; do not open the device. Menu labels may differ by version.

  1. 01

    Step 1

    Confirm the iPhone itself can browse over cellular data; if not, ask your carrier about the data service.

  2. 02

    Step 2

    Open Settings > Personal Hotspot, enable Allow Others to Join and note the displayed Wi-Fi password.

  3. 03

    Step 3

    Forget the old hotspot network on the second device, then reconnect with the correct password.

  4. 04

    Step 4

    Restart both devices and install available software updates.

  5. 05

    Step 5

    On supported models try Maximize Compatibility; before resetting network settings note that saved Wi-Fi, VPN and APN settings will be removed.

CHECK THE RESULT

How can you confirm the fix?

Connect a second device and open a small web page; compare Wi-Fi and USB connections where supported.

WHEN TO SEEK PROFESSIONAL HELP

When should you contact service?

If the option is missing or blocked by the plan, contact the carrier; for persistent dropouts contact Apple support.

⚠ Stop using a device if it overheats, shows liquid damage, smells burnt or has a swollen battery.

POTENTIAL COST

Will a repair cost money?

Settings, cables and user checks may require no repair. Hardware costs depend on the exact model, warranty and service diagnosis; no fixed price is promised.

FREQUENT QUESTIONS

Quick answers

Could these checks affect warranty?

Use only external checks recommended for end users by the manufacturer. Opening batteries, electronics or sealed parts can create safety and warranty risks.

What if the steps do not help?

Write down your model, software version and test results. Share those details with official support rather than repeating potentially unsafe actions.
