OnePlus 7 Pro and GSM vs CDMA

I've been researching for awhile. The standard OnePlus 7 Pro is attractive because i can get 12GB of ram, but it is GSM only, which is T-Mobile I believe. I read an article that said Ting would not be renewing their contract with T-Mobile and instead switching to Verizon. Will this affect the GSM users if this happens?

I also see that Best Buy has an option to buy the Sprint 5G version of the phone. I think it only comes with 8GB of RAM, but it can access both CDMA and GSM networks.

Does anyone have any thoughts on this?



  • Ting will want to retain its GSM customers, so it makes sense that they'll be lateraled onto Verizon. I don't know if they'll need a new SIM card. To retain customers, it'll be in Ting's interest to make this T-Mobile > Verizon transition easy.

    You have to decide if you want to connect via CDMA or GSM; the location where you'll use the phone may favor one system or the other. Ting's coverage maps can help with this.  I'm not familiar with that phone, but the GSM/CDMA version would allow you to connect to either system.

  • Network switches are happening in stages based on phone compatibility. I don't want to put anything in stone, because timelines change, but initially we'll be moving anyone who can move from T-Mobile over to Sprint with just a SIM card change. 

    As our VZW network isn't up and running yet, that's the step we're at now. In time, we'll be reaching out to customers as they're affected. 

    If you have a GSM-only phone that won't work on the Verizon network, come later next year you may not be able to be a Ting customer anymore without a new phone purchase. So, ye. If you buy the OP7 Pro that is GSM only, when it comes time for us to retire the TIng GSM network, you'll need to switch carriers or switch phones.

    I already universally discourage buying GSM-only devices with any specs (12GB of RAM does sound nice, though -- more than my college desktop) because it really does limit you to ONE or TWO networks when definitely other networks and programs exist. 

    If the Sprint 5G version from Best Buy is network unlocked, you should be able to access Sprint 5G (where available -- check for more) and 4G from a few other carriers, but we're in a weird place with 5G right now. Until it's standardized, if you buy a 5G phone for one carrier, there's no guarantee it's certified or will even work on ANY other carrier's 5G.

    That's one of the reasons I'm not buying any kind of 5G phone until it's standardized like 4G LTE was (remember WiMAX?).
