Swapping a Number from a CDMA Device to a GSM SIM Card

Follow

Last updated by Isabel M

Follow the steps below to activate a GSM SIM card by swapping a number from one of the other CDMA devices already on your Ting account.

Just make sure to check the device you want to bring to Ting

 

1. Confirm that your device is compatible with Ting on the GSM network.

 

2. Sign in to your Ting account online using your Ting, Amazon or Persona login information.

 

3. Click Device settings.

 

4. Click on the device with the phone number that you want to move and then click the edit icon in the Device row.

 

5. Click Switch devices.

 

6. Select your Ting GSM SIM card from the drop down list and click Done.

 

7. Your number swap should take take about 2 hours (24 at the very most).

Once the swap completes you'll get an email from us to let you know. If you have a device, install your SIM card in it once you receive this email. The email will include a link that will direct you back to your final activation steps for your device.

For now, sit back and relax!

    Is this the same process going from GSM to CDMA? I have a Nexus 5 and there may be times when I would rather be on CDMA than GSM depending on location.

    Basically, the same, but sometimes the Nexus 5 need some coaxing. Here is some information from another user.

    :

    1. This is probably the easiest way. Have your SIM eject tool ready. Go to the dialer and dial *#*#72786#*#* (note you must have the CDMA SIM in and have some signal for this command to work) and immediately remove the CDMA SIM. This will erase the CDMA carrier settings. Now put the GSM SIM in while it is restarting. It should automatically switch to GSM and pick up the Ting service but you will see a exclamation point next to the signal strength icon indicating a problem. That is because you haven't set up the APN yet. Go to Settings > More > Cellular networks > and you should now see Access Point Names. Create a Ting APN per the instructions at the beginning of this thread. Restart the phone and everything should work. 
    2. This is the other way that works... you don't need to do both. Go to Settings > More > Cellular networks > and change Preferred network type to "Global." Replace the CDMA SIM with the GSM one. The Access Point Names menu should appear (you may need to exit out of that settings menu and then return before it shows up) so you can add the Ting APN. Select the Network Operators menu and tap "Choose Automatically" which will register you on the Ting GSM network.

    I also want to keep the same number. I know just porting my number over to google voice and redirecting is an option, but that means paying for another line I may or may not use.

    You can port from Ting CDMA or another carrier to Ting GSM if it has not already been assigned a number. The partner does not allow changing the number assigned to a SIM.

    I just ported a number from T-Mobile yesterday in about a minute!

    Hey Joseph,

    The process of transferring a number from Ting GSM to CDMA is the same as outlined in the help article above. Feel free to submit a help request if you need any additional help!

    Thanks Bruce! Your comment fixed my CDMA -> GSM activation :)

    You're welcome. I have found out that carrier policies vary widely for porting. Sprint's pouring in is generally delayed after device activation. Ting's GSM partner starts the port when the SIM is activated.

    I'm currently testing out two samsung g3 devices, one from tmobile, one from att.  I'd like to move the gsm sim from one to other to see how well they work before I port both my numbers from vzw to ting.  I have activated the tmobile g3 and a new sim and ported one number over from vzw.  Now I'd like to move the sim with ported number to the att g3.  I didn't see a way to do that going thru byod instructions.  I only see option to choose 2nd (unactivated) sim card I have.  Is my only option to activate the 2nd sim card with a new number? And then port my vzw number to the 2nd sim?  Thanks.

    Maciej ,

    You just need to move the SIM to the other phone and configure it. It is really the SIM that is on your account, not the device.

    Hello, I am interested in purchasing a GSM unlocked phone on Amazon and transferring my current phone number from my CMDA Ting phone. This may be a dumb question but is it possible to access the Ting CMDA network? In other words: can one switch from GSM to CDMA on Ting? Thank You.

    RUBEN,

    I have switched from Ting CDMA to GSM. I am sure you could also go from GSM to CDMA.

    Your post is confusing, but since you are looking to buy a GSM phone, I assume you meant from CDMA to GSM..

    By the way, T-Mobile phones are the most compatible and do not need to be unlocked for Ting GSM.

    Hello Bruce, sorry for the confusing post. Like you said, GSM phones are very versatile and that is why I am considering buying one. The only problem is that the best coverage where I live is using CDMA. That is why I was wondering if switching from GSM to CMDA is possible at all on Ting.

    You should be able to switch back. Call, email, or chat with Ting support to get the official word, though.

    I am just a fellow Ting user.

    Hey Godfrey!

    Based on that model of device, it won't be able to be unlocked from the Sprint network to be able to use another carrier.. take a look at Sprint's unlocking policy for more information regarding this https://www.sprint.com/legal/unlocking_policy.html#!/

    so what do i do Jamie because in all ways i want to use a different carrier because am out of the US and not yet meant the policies

    I believe if you are going to travel outside the US, Sprint cab unlock the phone for International use so you can use a different carrier when outside the US. You would need to contact Sprint directly, though.

    Hello Godfrey --

    Are you already on Ting?  If so, check the following link about how to get an international SIM (UICC) unlock. Basically, Ting does the unlock for you, but it may not work if Sprint does not allow it. In my case Ting successfully got Sprint to give me the UICC unlock. I travelled overseas earlier this year, bought a prepaid GSM SIM in the other country, and used it with no problems. Then when I got back to the U.S. it was easy to switch back to the Ting CDMA network. Note that you will have a different (local) phone number while using the GSM SIM in the other country, not your U.S. Sprint or Ting number.

    I have an Unlocked S7 that is currently activated with Ting on CDMA. I want to try it on GSM and preserve my number. According to this discussion, this is entirely possible and I should be able to do it myself without contacting tech support. I want to confirm that I have understand that correctly.

    Second question. When I keep the same number but swap the device, will this be seen as 1 active phone for the billing period, or two?

    You probably need to contact Ting support for the official answer.

    My understanding is that there will be 2 devices for the first month, but I think one of them will be prorated.
