Common data questions answered
How much data do I need for 7 days of international travel?
A 7-day trip needs about 2.4 GB for light use: browsing, maps, messaging and social apps. That is what the calculator above returns for the Casual traveler profile. Heavy use needs far more. The Remote worker profile, with daily video calls and streaming, comes to about 26 GB a week. For light use, a HelloRoam 5 GB plan covers a full week with room to spare.
How many GB are needed for 2 weeks of travel?
Two weeks of travel typically needs 6-10 GB for light users and 20 GB or more for heavy streamers. If you want to know how much data do I need for travel 2 weeks running, use this calculator to enter your actual daily habits and get a precise estimate. Using your phone abroad for maps and social media adds roughly 1-2 GB per week on top of your base usage.
Does texting count as data usage?
Standard SMS texts do not use mobile data. App-based messages through WhatsApp, iMessage, and Messenger do use data, but the amount is tiny. A full month of heavy messaging uses less than 0.5 GB total.
How many GB of data do I need for travel per day?
Most travelers need 0.5 to 1 GB of data per day for normal use. Heavy video streamers can use 3 GB or more per day. For a 10-day trip, budget 5-10 GB total for typical use. This calculator estimates your daily usage based on your actual app habits.

How much data do I need for 10 days in Europe?
Ten days in Europe typically needs 5-10 GB for casual use and 15-20 GB for heavy streamers. That works out to 0.5-2 GB per day depending on how much video you watch. A HelloRoam 10 GB plan is a solid fit for most 10-day trips.
Does T-Mobile charge extra for roaming?
T-Mobile charges roaming fees or throttles data when you use your phone abroad on some plans. To avoid T Mobile roaming charges, many travelers switch to a local eSIM. A HelloRoam eSIM connects you to local networks in 185+ countries at flat data rates, so you know exactly how much it costs to use your phone abroad before you land.
