KnowRoaming’s new eSIM lets travelers in the United States and Europe add a new roaming SIM to their late-model iPhone or iPad, just by scanning a barcode. So, if you’re already on vacation, and you can’t bring yourself to speak to the locals, you can easily sign up and get started — all without a physical SIM card.

Correction: This story has been updated to accurately explain how Airplane Mode works.

A family from San Jose, California, returned from an overseas trip with several memories. But the strongest may be the one that greeted them at home — an iPhone bill with more than $13,000 in data charges.

The Chung family prepared for their trip to Vietnam with a firm rule that the iPhones would be on Airplane Mode to avoid roaming and internet fees. So it appeared son Nicholas Chung was in trouble when the T-Mobile bill showed the sky-high data charges coming from his number over a 30-minute period.

If you’ve ever traveled to a foreign country with your iPhone or iPad, you may have come across the dreaded No Service error. This happens when you get off the plane and switch on your iPhone. But instead of connecting to a cellular network, your iPhone just spins its wheels and refuses to connect.

Apple offers a support page to help out, and a zillion forum pages serve up advice, but none seem to cover this particular tip, which I discovered after hours of painful futzing with settings.

tech travel tips Your mobile data plan takes a hammering when you travel. All the stuff you usually do while sitting in bed using your home Wi-Fi — like reading Cult of Mac and viewing cute capybara GIFs — will eat through your monthly allowance. And that’s before you get to the extra use of maps and Google to find your way around.

Today on Tech Travel Tips, we’ll look at ways to stop your iPhone and iPad from using up all your data in the first few days of your vacation.

Today, roaming charges have been dropped across the European Union. If you live in Berlin and travel to Budapest, you can keep using your existing data plan at no extra cost, and you keep (more or less) the same data allowance. That’s neat for Europeans, but it’s also good news for international travelers, because you only need to buy one SIM card at the start of your trip, and then you’re covered until you go home.

Mobile-To-WiFi Roaming: A Dream For Carriers, A Nightmare For Users

By

Wi-Fi roaming could free up spectrum, increase user experience but at what cost?

Carriers are constantly talking about the limited spectrum available for mobile devices. That’s the reason that give for instituting data caps and throttling heavy users. It’s reasonable to assume that carriers exaggerate the real issues somewhat when the trot this argument out as a case for data caps and tiered data pricing (they make a lot of money that way), but it is true that radio spectrum is a finite resource. With Cisco predicting an 39-fold increase mobile traffic use will over the next four years, carriers will need to find creative ways to manage the slices of spectrum that they have.

One option is to offload service to Wi-Fi networks. All iPhone (or other smartphone) users do this already to some extent when we connect our iPhones to our home networks. They deliver better performance and let use as much data as we want without having to worry about it impacting our next bill. Two mobile trade groups are looking to turn this same offloading model into a large scale option for carriers to deliver better mobile broadband while taking the load off their 3G or 4G networks.

Starting April 5th, T-Mobile will begin capping the Domestic Roaming Data Allotment. Unlike their data throttling, once a user goes over their designated allotment,they will simply be cut off from data altogether, until they return to the T-Mobile network or connect via WiFi. While this change is unlikely to affect the majority of us (when’s the last time you used data while roaming?), T-Mobile will send out warnings via text message when your domestic roaming data allotment has reached both 80% and 100%.
