        Wait… How can you not be a CDMA network and also not work with GSM phones?
        What 3rd networking system do you think Virgin is?

          CDMA and GSM are compatible.. you can take a verizon (CDMA) phone and hook it on to at&t (GSM). This is FACT. I’ve done it! As long as the phone is both CDMA and GSM compatible, it CAN be done.

            StuffYouShouldGoogleBeforePosting says:

            You just contradicted yourself in that post. Most phones today have both CDMA & GSM antennas but a phone designed for CDMA-only will NOT work on a GSM-only network (and vice versa).

            hell you can do it with a ham radio and a digipeter, just need input freq to trip switch and the pairs freq. you talk on one freq and listen on another freq, called pairs

            Starrla1979 s right…. if you use one iOS on the front and one iOS on the backside you have a secure connection. These companies are baffleing you with technology terms and tech garbage talk. I get free tele all the time with a ham radio..pipe into any system with a little knowledge that is free for the looking.

            Eric B A clarification is needed. Your PHONE is compatible since was made to use both GSM & CDMA. The formats are NOT compatible.

      If Virgin (Sprint) is using LTE or WCDMA Multi-Band on their network, do the following.

      HTC One-M8 – Change Network Mode Settings
      For International Carrier (Unlocked) Phones

      Change Network Mode Settings:
      From a Home screen, tap Apps Apps icon (located at the bottom).
      – Tap Settings. (Note If unavailable, tap the Dropdown menu Applications dropdown menu icon (located in the upper left) then tap Alphabetical. If still unavailable, refer to Manage App Icons.)
      – From the WIRELESS & NETWORKS section, tap Mobile data.
      – Tap Preferred Network.
      – Select the appropriate setting:
      LTE Mode – (This setting should only be selected if experiencing service issues in locations that offer multiple network types and only LTE is needed.)
      LTE/Legacy 3GPP Mode – (This setting should only be selected if experiencing service issues in locations that offer multiple network types and only LTE/legacy 3GPP mode is needed.)
      Global Mode – (This is the preferred setting for most locations)

      Note: In Global Mode, the preferred international carrier is automatically selected. You can manually select an alternate carrier by navigating: Apps > Settings > Mobile data > Network preference > choose carrier from list then tap OK.
      Note: It may require as many as 6 registration attempts with that carrier prior to successful registration.

    • Connor Miller
      Connor Miller says:

      Dude before you get this, I have the unlocked D801(AT&T), but with a T-Mobile SIM card, but because it is a at&t phone, I can never get a software update because I am using a T-Mobile SIM card. This might be the same case with the phone you want to get. But, even without the update, it is running android 4.4 and the lg g2 runs it fast and easy. Check on it and good luck!

    I need to switch from the bums at Tmo after I just bought a phone from them. Then they shut me off. It wasn’t for non payment, it’s because a communication company can’t communicate. My Bill reflects a minus. But they said that I complained about their service. While true, it took them a year and a half to get it marginal. So I buy a new phone from them, and they shut me off.

    • Rringo
      Rringo says:

      Gsm means at@t/tmobil networks..Verizon has the best coverage all around..tmobil has the highest transfer of data but is limited to large towns and major highways. .do you use a lot of data? Or do you use it only occasionally to access the internet and make phone calls? I’ve got great plans for the 3 big networks,,no contracts,wholesale..way cool stuff.

    • Rringo
      Rringo says:

      And meid# check would reveal if your phone would qualify for the tmobil network. If your phone is currently working on the sprint/Verizon tower’s it is unlikely your phone would work on pcs metro..the exception would only be if your phone was unlocked to all of the carriers..a simple meid#check would reveal this quickly. Most blu phones work exclusively on the tmobil/at@t network system ..you will need to get a sim card from one of those carriors..should work great..those phones look real mice. I have sim cards for tmobil,at@T ,SPRINT AND verizon devices..

      Hello Diane,
      Unfortunately, it is not possible to use your AT&T Galaxy phone with either carriers. You will need to buy a Verizon or boost device.

    Del says:

    I recently purchased the OnePlus 3 and I live in a very rural area, Verizon is my best bet for this area but it’s CDMA and the OP3 is GSM. Now I’m getting ready to move to a more metropolitan area but I’m sure I’m going to be traveling back and forth from the city to the country. I hate the fact that the OP3 doesn’t carry that strain of 4G LTE….that’s pretty much my only complaint. I only see one carrier that’s GSM and uses Verizon towers but I don’t believe I can get it in my area.. I guess I’ll have to stick with AT&T… Even though it’ll be a dead zone in my country home.

    I just bought a BLu Studio Plus One , S0130UU cell phone .
    I bought it because I thought or was told it would work on Freedom Pop.
    Now FreedomPop is telling me it’s not able to activate the phone. It can take 2 sim cards or one sim & sd card memory expansion.
    I am an older man & a newbie to all this cell stuff.
    What steps do I take to activate this phone ? Do I have to get a Sim card before I can activate it ?
    Any help would really be GREAT !
    Thanks very much .

    • alain smithee
      alain smithee says:

      Freedom Pop is a CDMA carrier, and they use Sprint towers, while the phone you bought is a GSM phone. It’s like not being able to listen to AM radio stations with an FM radio, or vice versa.

      If you want to use Freedom Pop, you will need an unlocked CDMA phone. If you want to keep the phone you have, you will need to find a GSM carrier.

      Flash wireless has a nice tmobil plan with unlimited talk and unlimited text with 1 gig of data, no contract starting at around 40-50 bucKS a month..there are bigger single plans with up to 6 gigs of data..I’ll help you with it..piece of cake..plus when you refer 5 friends and family and they get service , your service is free month after month..this also applies to verizon and sprint plans

    I have but one question.
    Is the phone’s preference towards CDMA or GSM a hardware thing or a software thing?
    Like if I took an Android phone and modded the Software, could I get it to work with whichever networking system I want, or do you think thats not possible?

    • Rringo
      Rringo says:

      Android and apple phones are made for both sprint /Verizon. And tmobil/at@t networks..most phones are tied to one or the other..however I’ve heard wind that flash wireless may be coming out with network open phones that will operate on either systems,,simply a sim card change..would rock the phone world when that happens

    I have a Galaxy note 4 phone with tmobil. Trying to unlock and use phone with safelink as my carrier. I have received unlock code from tmobil and instructions on unlocking gal note 4 so I can use it with safelinks SIM card. However, when I turn on phone with safelinks new SIM card there are no windows available to enter the unlock code or any other of the prompts listed in the instructions provided by Tmobil. The tech at tmobil said they may be on different networks but when I did a little digging it appears that both tmobil and safelink are both on GSM networks. Any help would be appreciated. Thank you.
