T-Mobile to start selling 3-in-1 SIMs, plus $10 unlimited talk & text 7-day prepaid plans


Along with news that the popular 2 for $100 and 4 for $100 plans are ending soon, we’ve been informed that T-Mobile has a couple more interesting changes on the way. We’ve been shown the company’s plans for the rest of June, and there were two more little tidbits of information I felt would be good to share with you.


First off, from June 15 (this coming Monday), T-Mobile retail locations will begin receiving TrioSIM packs. As you’d expect from the name, the SIM is made up of all three standard SIM card sizes: Mini, Micro and Nano. The aim – of course – is to make it easier for customers to switch devices without having to get a brand new, different sized SIM card as well. Screen Shot 2015-06-13 at 20.54.06

T-Mobile in Europe – in the Netherlands, for example – already uses these TrioSIMs, as do a couple of carriers in the UK.

The idea is that if, for instance, you change from a modern iPhone to a device like the Samsung Galaxy Note 4 or LG G4, that you can just insert the Nano SIM back in to the Micro SIM-sized adapter, and carry on using your same SIM card. It saves you hassle, and presumably will save T-Mobile some cash. And I don’t mean just the cost of the SIM card replacements, but the time spent by store and care staff dealing with SIM card replacements. It’s also great for serial phone-swappers like me too!

Seven day unlimited talk and text pass

As well as these new, super-useful SIM cards, T-Mobile is also going to launch a brand new short-term prepaid plan (or add-on). From June 28th, T-Mobile is going to roll out a 7-day, unlimited talk and text pass for prepaid customers. It costs $10 for one week’s use and is being pitched as a “great option for tourists and customers looking for unlimited usage for a short window of time.” 

The One Week pass – when it launches – will need to be added to the Pay as you Go Plan for customers looking to take advantage:

Both changes seem like positives on the surface. As a phone reviewer, the TrioSIM is the one that excites me most. It would mean that I can use my main SIM card in any phone I want without having to worry about whether it takes a Nano or Micro SIM. Stay tuned for more on this, and let us know what you think.

    Both trio sim and $10 for a week are great options for people who only need more data for a week. Awesome having really fantastic options.

    • 21stNow

      Did I miss something? I only saw unlimited talk and text; no data was included.

      • JaswinderSinghJammu

        My bad. I thought it said data as well. Personally I think T-Mobile would be smart to include data as well. May be charge $15 for all 3.

    @ Cam Bunton – “As a phone reviewer”, I wish you knew SIM adapters cost less than a dollar from online outlets. Google’s your friend. Or Bing. Or Yahoo. Or DDG. Or SP. Or IXQ. You get the idea.

    SIM cutters are also available for around a buck or two, meaning you can cut a micro SIM down to Nano and then use the adapter to use the same SIM in every phone you’ll ever use, irrespective of whether it uses Nano or Micro.

    • qmc

      Yep. I got 3 packages of 3 NOOSY adapters (nano->micro,nano->mini,micro->mini) for $5 from their authorized ebay reseller for $5. $1.67 each. Comes in a wallet-sized thing. Gave away 1 set, going to give away the other. Good reviews, worth it, and sturdy enough not to snap or give me busted pins.

      • JaswinderSinghJammu

        Yeah, I bought one of those and messed up the pins on my phone, I am just glad it was a extra Lumia 521 from a couple of years ago. I wouldn’t buy any of those adapters.

        • qmc

          I know from reading Amazon reviews there are some fakes out there (really? who counterfeits a less-than $1.50 item?). Hope you didn’t have one of those. I’ve been using them in a HP Veer, galaxy S3, and a Moto E with no signs of trouble. There is no gap for the pins to get caught in (unless of course you put the adapter in without a SIM card… bad idea)

    • Cruise Guy

      This is a news article. Not a review. Of course he knows that. This is brilliant because 99.99% of the people won’t use a sim cutter, or a scissor or order from an online store. That’s only for techies, not mothers and grandmothers.

      Instead, they will look at the sim, scratch their head, and say wrong size-T-Mobile sucks. Then they will call T-Mobile and cost the company money asking questions. Then they will go to the store, and wait in line (lowering customer service), and wasting a reps time to get a new sim, and have them verify the account, and change to a new sim card number. In the mean time, I will be wanting to buy something, but will have to wait for this customer have their sim card replaced.

      Bravo for T-Mobile for simplifying the process first in the US market. I see this has been going on in other parts of the world for T-Mobile for some time now.

      • Greg Lee

        Or maybe they’ll just ask one of their children or grandchildren what’s a SIM card for and can you tell me what size I need for the phone you bought me for my birthday.

        Sheesh, what an imagination you have.

      • squiggleslash

        So, uh, why doesn’t this happen with the SIM cards T-Mobile distributes separately from phones already, which are full sized with a punch out to get a Mini SIM?

        As an aside, who here has actually ever used a phone that took full sized SIMs? My very first was a Motorola Graphite, a one2one (UK network) exclusive, which took the full sized SIMs. Every GSM family phone I’ve had since, on both sides of the Atlantic has taken the mini size… I wonder if they still make any?

        • Logan C.

          full size SIM cutouts only exist now to carry the barcode information for the mini (which I think you’re referring to as “full size” which is the entire card) and smaller SIMs. Pretty much half of the T-Mobile prepaid offerings take mini SIMs (basic and low end Android) and a LOT of people come from overseas with their unlocked dumbphones they only have for vacationing, which also take mini.

          tldr yes they do, also full size = entire card, mini = largest cutout, micro, nano.

        • 21stNow

          I was wondering if anyone in the US had ever used a full-sized SIM card, as well. I was late switching to the GSM game (2004) and only saw mini-SIM cards and smaller.

          To Logan C., squiggleslash is referring to full-sized SIM cards, not mini-SIM cards

    • Cam Bunton

      Yep, I have two cutters and many, many adapters. I’d rather not have them.

  • pmichos

    I recently purchased a phone from t-mobile online and it came with one of these cards.

    • ChristianMcC

      No BS? That’s cool. I’ve been using a sim adapter for a bit, so not as important for me, but that’s still good to hear.

      • vinnyjr

        I also use adapters, I’ve also ruined my Sim card tray using these adapters. You must be careful inserting & removing these adapters, I’m sure these new Sim cards won’t have this issue. My old SGS3, had to replace the Sim card tray. Thanks again T-Mobile.

        • John Wentworth

          I’m not sure I agree, they might be bringing more trouble on themselves encouraging sim tray usage. they can be dangerous, especially in the hands of people who don’t know what they are doing and aren’t careful.
          Some sim tray designs are better than others too, so in some phones they may be fairly safe while causing damage in others.
          I find the sim trays like the nexus 5 that have a actual tray that moves in and out much easier to use with a sim card adapter than slide under designs which are more prone to damage.

          It’s a lot easier and cheaper to replace a sim card than repair a broken sim tray.

    • Kenneth Warner

      What phone was that?

      • pmichos

        LG Leon LTE

  • Philip

    I thought all the new phone are using nano SIM. Maybe the TRIO is for those that use phone that is few years back?

    • JLV90

      Pretty much every flagship phone released after the Note 4 has had a Nano SIM, the only exception is LG G4 which still uses Micro.

      • John Wentworth

        I think all phones should hurry up and switch the the nano standard, not because it’s great or anything but just to stop the annoyance of multiple sim card sizes.

        If all android phones had decided that nano was an apple only thing I would have been ok with that too, but with some androids embracing nano and some sticking with micro, it’s just a pain in the butt.

        I’m currently using a sim tray for my work sim because I had cut it to use in a 2013 moto x, thinking nano was the way to go and more and more androids would start using the nano size. a year after I cut that card and not much movement on sim card sizes in android phones.

        the sim tray is annoying and worries me as it doesn’t move as smoothly in an out as a normal micro sim. they need to move to nano and stay there.
        they don’t have enough room to make the card any smaller without re engineering it or moving to some sort of virtual sim

  • kiblawi2000

    Also, this will probably help on inventory costs, only have to stock one kind of sim instead of three different Sims

  • carol argo

    Yes.finally .now that’s is go a be usefull

  • vinnyjr

    Great idea with the Sim cards. I change phones almost every other month, I know others that also switch phones like I do, great move T-Mobile. I’ll be ordering my new Sim card as soon as they become available. Thank you T-Mobile, Thank You John Legere.

    • NinoBr0wn

      Really every month? Do you get bored or do you just like having options?

      • Acdc1a

        Probably the constant search for the perfect phone. It doesn’t exist.

  • Fuego

    I sold 4 phones today, 2 of those phones already came packaged with this new triosim! Super cool!

    • Kenneth Warner

      What phone?

  • chanman

    That tourist option is brilliant. I’ve been to a few countries where they prominently offer packages like that at kiosks in places like the airport and they’re usually swarmed – about time for USA to get on board (from a major national carrier, that is). Probably will be a great revenue generator

  • Harp

    Trio SIM doe not excite me at all. 7 day plan is OK. At first I thought that trio SIM meant 3 lines on 1 SIM card.
    BTW, is it possible to get 2 phone lines on 1 line/SIM/phone. Please dont tell me about google voice. I know that already.

    • disqus_r8vNDdBDEk

      Sure! Just buy a dual sim phone. Check Amazon.

    • Herb

      You could use Google Voice.

  • Mike Palomba

    Does this sim let you convert, say, from full size, to nano, back to full size? Or from full size to nano then to micro? I like to use my android device sometimes and that takes a micro sim but it’s a pain because my iPhone takes a nano.

    • Medion

      Yes, as long as you don’t lose the two extra pieces. It’s basically just a Nano Sim with micro and standard trays.

      • Mike Palomba

        That’s awesome, I have to get one of those soon lol

  • notyourbusiness

    The trio SIMs would have really been great a couple of months ago. I normally use Windows Phone with a micro SIM, but last month I bought a nano SIM in a T-Mo store to possibly use with my iPhone 5S (haven’t actually activated that one although it’s in the iPhone). 15 dollars for the trio would have saved me a little money.

  • qmc

    The odd thing is they already sell things like this — e.g. bestbuy in stores and online (I know if I link it will reject it, but ”
    T-Mobile – Complete SIM Starter Kit – White”
    “This T-Mobile complete SIM starter kit includes a nano SIM card with micro and standard SIM adapters, enabling you to activate T-Mobile’s no-contract, nationwide 4G LTE service on select phones and tablets.”

  • Lester Walters

    Instead of moving your SIM from device to device and risk damaging your phone with these adapters, why not implement SNMS? With single number, multi-SIM you can have a number of devices with the same number and not have the hassle of swapping SIMS.

  • Jacob Azriel

    If I have the $30 plan can I get this 7 day pass to get unlimited talk?

  • Jeffrey Wang

    I live in the Dallas area, called one T-Mobile store, they said it’s shipping in two to three WEEKS. I’m going to call some others too.

  • thepanttherlady

    All links go to moderation (to try and cut the spam). I was explaining that if the link is legit (not spam), I approve it when I see it come through.

    • Jeffrey Wang

      I completely understand and now I know :) Thanks for the speedy approval!
