Hi everyone,

I’m planning to use a 5G router for my home internet in Germany. I’m looking at two options from Vodafone, but I’m a bit confused about the price difference.

  1. Vodafone GigaCube: A dedicated home internet product that includes a 5G router.

  2. Regular 5G Mobile SIM: A standard smartphone SIM (with calling/texting) that I would just plug into my own 5G router.

Both offer 5G speeds and require a 24-month contract, but the regular 5G SIM is slightly cheaper than the GigaCube plan (excluding the initial GigaCube discounts).

Are there any specific technical or contractual restrictions when using a regular mobile SIM for home internet? Since the mobile SIM is cheaper despite having more features (calls/SMS), I suspect there might be a catch—like data throttling, lower network priority, or "Fair Usage Policies" that don't apply to the GigaCube.

Has anyone tried using a regular Vodafone 5G SIM in a stationary router? I'd appreciate any insights!

  1. Look at telekom hybrid contracts, can end up cheaper and you get the low latency/reliability of a wired connection on top.

  2. I’m not expert at all, but the first thing that came to mind for me was that the Gigacube is a router, so you have LAN and can easily connect multiple devices to the internet via Wlan, while having a sim card would restrict you to one device (except you always put up a hotspot with your phone or something like that)

  4. The regular SIM card is not unlimited. You get 123 GB “fair use” and then have to pay 0.13 cents/MB. Didn’t find anything like that in the GigaCube one.

  5. I don’t know your reason for doing this, but I am doing the exact same because I think internet prices are absurd here and I can’t believe we have to rent their routers.

    My advantage is that I qualify for a young discount, so having that in mind I’m using Telekom instead of Vodafone, (I was using O2 prior to that but 5G coverage is a joke, at least in my situation).

    With Telekom I have an unlimited data contract where I plug the sim into my own 5G router, and also they offer multisim at no additional cost, so me and my partner can use the same sime on our respective phones (even though that does not give us our own number) to access the same good coverage on the go.

    Tbh Telekom is a bit more expensive but in my short experience is proving to be worth every euro
