Common data questions answered
How much data do I need for 7 days of international travel?
This calculator estimates about 2.4 GB for a 7-day trip with light use. That is the Casual traveler profile above: maps, messaging, browsing, music, social media and app updates. Heavy use needs far more. The Remote worker profile, with daily video calls and streaming, comes to about 26.2 GB a week. Pick a plan with a little more data than your estimate.
How many GB are needed for 2 weeks of travel?
This calculator estimates about 4.8 GB for 2 weeks of light use, the Casual traveler profile. The Remote worker profile, with daily video calls and streaming, needs about 52.3 GB for 2 weeks. Video makes up most of the difference. Enter your own daily hours above to see what your 2 weeks will take.
Does texting count as data usage?
Standard SMS texts do not use mobile data. Chat apps like WhatsApp, iMessage and Messenger do use data, but very little. In this calculator, an hour of messaging every day comes to about 0.1 GB a month. That is small next to video, so messaging rarely uses up a plan.
How many GB of data do I need for travel per day?
This calculator estimates about 0.3 GB a day for light use. That is the Casual traveler profile: maps, messaging, browsing, music, social media and app updates. The Remote worker profile, with daily video calls and streaming, uses about 3.8 GB a day. An hour of HD video alone uses about 1.4 GB. Set your own hours above to see your daily figure.
How much data do I need for a 2-week trip if I stream video?
Your data use depends on your habits, not the country. In this calculator, two weeks of light use comes to about 4.8 GB. That covers maps, messaging, browsing, music, social media and app updates. Each hour of HD video you stream adds about 1.4 GB. HelloRoam eSIM plans cover 185+ countries, so you stay connected from day one.
How many GB of data do I need for a month of travel?
This calculator estimates about 10.4 GB for a month of light use, the Casual traveler profile. The Remote worker profile, with daily video calls and streaming, comes to about 113.3 GB a month. For heavy use on a long trip, a HelloRoam unlimited plan can be the simpler choice. Fair-use terms apply.
How much data does video use on a week of travel?
Video is what pushes a week's total up. An hour of Netflix or YouTube each day for a week comes to about 9.7 GB. An hour of video calls each day for a week comes to about 6.5 GB. Light use alone stays near 2.4 GB for the week. Change the hours above to match your own week.
What size data plan do I need for a 10-day trip?
For 10 days of light use, this calculator estimates about 3.5 GB, the Casual traveler profile. The Remote worker profile, with daily video calls and streaming, comes to about 37.8 GB for 10 days. Most of that gap is video, so your video habits decide the plan size you need.
Does T-Mobile charge extra for roaming?
It depends on your plan. T-Mobile sells International Passes for faster data abroad, and each one needs a qualifying T-Mobile plan. To avoid T Mobile roaming charges, many travelers switch to a local eSIM. A HelloRoam eSIM connects you to local networks in 185+ countries for a set prepaid price, so you know what your data costs before you land.
