Don't Pay For Roaming Charges! How to Use Cellular Backup Calling

Traveling can be a hassle, especially when it comes to staying connected. You might end up being somewhere with no service or you have to spend money on an international data roaming add-on from your carrier. With Cellular Backup Calling, you'll be able to stay connected and still receive important calls and texts while you’re away from home. This video tutorial will show you how to set it up on your phone and I'll also talk about some of the downsides of using this feature.

Additional information - Make sure that you have enough minutes & text on your primary line. If your primary carrier has roaming capabilities you might be able to disable roaming before you travel, so check with your carrier first.

Thanks for this video. Exactly what I needed. Almost eerily close to what I need. I'm using Tello on an iPhone 12 mini too. One question: My secondary line that I'm using for data is Google Fi, which does have voice and text capabilities too. When I just tried this, even though Tello was set as my primary voice option, it switched to Google Fi when making the call. I tried it again and had to select "Always use Tello with this contact" in order for the call to go through Tello. Is there a way to do that for all calls? Make it so that it always uses Tello over Google Fi data instead of automatically switching to Google Fi for calls?

older non-techie here. I'm so confused! I have the inverse situation? I have Claro with vowifi (no roaming) as primary and US Tello (no roaming) as secondary. Tello supposedly has vowifi but I can't get it to work. Tried every combination and still can't receive or make calls. Could you make another video perhaps?

Cool video but will it work with data on a standard SIM instead of esim?

First of all, thank you for the nice explanation. I am using Xiaomi Mi10 (umi). With Vowifi on my phone, I can talk and receive messages abroad over wifi. However, I cannot make backup calling via data sim. Is there any way to solve this?

Does the "cellular backup calling" work on all iPhone versions, i.e., US and international versions?

If you went with a more premium cell provider that allowed mms would that then be possible over the cellular data or is there no work around for that?

Do you still have the feature after you update it to android 14? I heard it’s removed from android 14
