sim in mifi router

Hi ​@Michaelam,

I’m really sorry you’re having trouble with this I can imagine how frustrating it is, especially when it was working initially and then suddenly stopped after the router powered down.

Let’s go through this clearly.

⚠️ Important point about routers (MiFi)

Although you were advised it would work, iD Mobile SIM-only plans are designed primarily for use in mobile phones, and service in routers/MiFi devices isn’t always guaranteed or supported long-term.

That said, since it did work before, there’s a good chance this is a settings or connection issue rather than a full restriction.

🔧 Things to try
1️⃣ Reinsert the SIM

• Power off the router
• Remove the SIM
• Reinsert it carefully and power back on

This can help the router re-register on the network.

2️⃣ Manually re-enter APN

Even if it looks correct, re-enter it fully:

• APN: id
• Username: (leave blank)
• Password: (leave blank)

Then save and restart the router.

3️⃣ Check network mode

If your router allows it:

• Set network mode to 4G/LTE only (or Auto if that fails)

4️⃣ Check data / spend cap

• Make sure your plan still has data available
• Ensure there’s no bill cap or restriction blocking usage

5️⃣ Try the SIM in a phone

This is a key test:

• Put the SIM into a phone and check if data works there

👉 If it works in a phone but not the router, the issue is likely device compatibility
👉 If it doesn’t work in a phone either, it may be an account or provisioning issue

6️⃣ Reset the router (if possible)

A factory reset of the MiFi device can clear any corrupted settings after the battery died.

❗ Why this may have happened

When the router lost power:

• It may have lost network registration settings
• Or failed to reconnect properly to the iD/Three network
• Some routers can also behave inconsistently with certain SIM profiles
