Using Mighty Mobile Unlimted Plan in a Router

BlackLab on 26/03/2026 - 13:26

Has anyone been able to get a Mighty Mobile phone plan working in a portable wifi router?

We're going to be moving house so I purchased a 5G portable wifi router and Mighty Mobile unlimited plan instead of signing up to a new 12 month fibre connection.

I got it working for a few days but it stopped working and doesn't want to connect with the Mighty Mobile sim (2Degrees works fine). I can use the MM sim in a phone so it just seems to be the wifi router that's an issue.

Looking for ways I can use the MM plan otherwise I'll need to switch to starlink or something else for a few months.

    Maybe this is helpful

      Thanks. I've tried those settings but it still comes up with "No Service" (when using the MM sim)

      It’s working now!
      I went back through all the comments and made a few adjustments based on the feedback.

      I'm now getting 463Mbs Down / 79.9 Mbps Up

      The key settings I'm using are:
      Under Network → Mobile Network

      Network Selection
      * Network Mode: 5G NSA

      APN
      * APN Mode: Manual
      * APN: vodafone
      * Username: [blank]
      * Password: [blank]
      * Authentication: NONE
      * PDP Type: IPv4
      * ✅ Set as default

      Under System → Developer Option
      * Country/Region Code: NEW ZEALAND

        Glad it worked.

    I kind of regret sharing my trick (using 5G SIM to replace your broadband), as the more people who contact Mighty Mobile (or perhaps other vendors) about setting this up on a router, the easier it is for them to detect and enforce some sort of ban/block.

    If you're going to set this up, and it's not strictly within their TOS, then why would you contact them and potentially risk ruining this for everyone else?

    Not to mention, I already listed those instructions in my original comment in the other post, so that's all you need to make it work.

    Anyway, at least Mighty Mobile allows hotspot tethering in their TOS, which essentially is just what a router does. Worst case scenario, you just run hotspot tethering on a phone with good a good modem that can deal with multiple concurrent connections.

      That's mostly fair comment, but it's doesn't seem like a new 'trick' to use a SIM (5G or older) in a router to replace broadband - lots of people have been doing that for many years now, and some of the telcos (Skinny for sure at least) used to (maybe still do) explicitly advertise that as a product / service?

      Apologies if I'm missing something here.

    Works fine for me in the Huawei B525 but that's a 4G router. Haven't tried it in a 5G.

    • BlackLab on 26/03/2026 - 16:24

      Good to know.

      I'm using a ZTE U60 Pro, which is 5G router. I can set it to 4G but it still doesn't work with the MM sim.

  • Huntakillaz on 26/03/2026 - 23:57

    Just get a cheap 5G phone (or your old one) and a FritzBox router > USB Tether to the router and it works, without you needing to violate their T&C

    • LupinS on 27/03/2026 - 00:14

      I haven't even got that far yet. Just tethered to my desktop if I need any speed, and using that to share to everything else.

      And I don't even bother with that half the time and just hotspot from my phone. Which requires even less effort. But doesn't keep my phone charged.

      • Huntakillaz on 27/03/2026 - 00:16

        Yeah the router gives you wifi for the other devices, Ethernet ports and will keep the phone charged while minimal usage and drain on the phone

    Have you contacted Mighty Mobile and asked them what might(y) be the problem?

    You never know, it might be some obscure setting that you have to change in the router.

    • BlackLab on 26/03/2026 - 17:01

      Yep tried that. They said it's only allowed in a mobile device, not a router.

      • Alan6984 on 26/03/2026 - 17:23

        They said it's only allowed in a mobile device, not a router.

        Maybe that's the issue if you shook hands on a deal where you agreed not to use it in a router?

        • BlackLab on 26/03/2026 - 18:08

          Yes, quite possibly.
          However there are lots of people using it in a router. I’m trying to work out if it’s blocked at the network (IMEI), a device issue, or a sim issue.

          MM won’t provide any support if your using a router so they can’t help be diagnose the issue.

          • Alan6984 on 26/03/2026 - 22:38

            @BlackLab: Okay - well, good luck!

            • BlackLab on 26/03/2026 - 22:41

              @Alan6984: Got it working now. It was an issue with the settings on the device.

              I've added the details in a comment above for reference if anyone else need them.
