    Cheapest T-Mobile data SIM card

    By Rob Webber - Last updated on

    If you need access to Wi-Fi when you're travelling data only SIM cards can help keep you connected.

    With T-Mobile MVNOs you'll receive the same quality coverage, but their low cost plans can save you up to $600 a year.

    Mobile Virtual Network Operators are low cost carriers, operating on the same US networks, but at half the price. MVNOs have been growing in popularity and are one of the easiest ways to save money on your wireless device bills.

    We've compared all data only SIM cards with T-Mobile MVNOs for you to take a look at below.

    T-Mobile data SIM card sizes

    There are three different SIM card sizes. Each has an adapter in case you want to switch to a phone with an incompatible SIM Card slot.

    • Standard SIM Card - The original SIM Card size is similar to any card in your wallet. However, if you want to transfer your data to a new phone, you can take out a small portion of the SIM card to insert into another iPhone.
    • Micro SIM Card - Micro SIM Cards were introduced in 2010. The Micro SIM Card size is small compared to the original SIM card but not quite as small as the Nano SIM card.
    • Nano SIM Card - Nano SIM Cards are the smallest SIM cards that came out in 2013.

    How to remove a T-Mobile data SIM card

    To remove the SIM card from your T-Mobile device all you need is the SIM card remover tool provided to you when you bought your device or a small paper clip.

    1. If using the paperclip, unfold it and gently insert the end into the small pinhole in the SIM tray.
    2. Press gently until the SIM tray pops up, you do not need to use much pressure.
    3. Pull the SIM tray out gently, be careful the SIM card does not fall out.
    4. Swap your SIM card over, making sure you have aligned the SIM in the correct position.
    5. Re-insert the SIM tray into the phone.

    Recap

    Do you really need unlimited data? One of the first places you can save money on your data only SIM is by checking your estimated data use.

    On average we only use around 3 to 5GB a month, so by opting for a set data limit plan you could get more bang for your buck.

    You'll be able to access Wi-Fi where the T-Mobile network is available. So if you're traveling you can check cell phone coverage for any area with the ZIP code.
