Unlocked Huawei E5331 - "Network Access is not allowed"

I have a number of mifis, one of which just died and I'm replacing it with one I bought a couple of months back.

The replacement was tested at the time I bought it, using the SIM I've taken from the dead device, and worked perfectly.

Now, when I connect to the mobilewifi link (or 192.168.1.1) to check all the settings, they are all as they should be. (Right APN, username, logon etc)

And I've checked with Orange that the SIM is still valid and live on my account. It is.

They have no idea why the message:
"Connection failed. Network access is not allowed. Please contact your service provider."
is coming up. And nor do I.

Anyone here got a clue?

That's strange, unless the APN is the system default the reset should have cleared the data.  I guess it depends on the unlocking process, if they've just made it "any SIM" but retained the original provider's firmware those settings may be the default.

Just in case you should hold the button in until all the lights are off - it's between 5 and 10 seconds .

I'm pretty sure you won't have got that wrong but haven't got much else to offer right now :(

oh and I should have mentioned, I've checked it's unlocked status and confirmed that it is unlocked

The only time I've seen this on a Huawei MiFi is when the SIM isn't on a data plan and the provider wasn't allowing tethering - but you say this SIM was working fine for data previously?

Have you tried a hard reset with the SIM in place?

Data plan is fine according to Orange and the Sim was working in the now dead mifi up until at least 5 pm on Friday.

Didn't know how to do a hard reset on this device but good suggestion. Googled it. Pressed the reset switch till all the lights flashed a few times.

Went back to 192.168.1.1. No change. It even retained the APN data which I was expecting to have to re-enter.

Does that mean the reset failed or do we not expect the reset to erase APN data?

We may have a resolution. I tried the modem with a different (PAYG) Sim and managed to get it functioning, so despite Orange's assurances that there could be no problem with the SIM or contract, it looks like they were wrong. I gave them a detailed description of my efforts, failures and successes last night and they accepted that the SIM looks guilty. They're sending me a new one.

I think you're right about the reset and APN data, though, so there may still be another issue once I get the new SIM. I reached this conclusion after attempting a reset on the dead mifi. It didn't fix anything but it definitely wiped the APN data.

So I'll close the issue now and happily give you full credit for helping me eliminate options and focus on the real problem.

Thanks

another example where the expert hasn't necessarily provided a solution but by asking the right questions or offering a suggestion has reduced the options and exposed the real problem.
