Choosing the right amount of mobile data is one of the most important decisions before traveling to Greece. Buy too little, and you may run out of data halfway through your vacation. Buy too much, and you may pay for data you never use.
The good news is that most travelers don’t need unlimited data. The ideal plan depends on how long you’re staying, how often you’ll use hotel WiFi, whether you’re visiting several Greek islands and how much time you spend streaming videos or uploading photos.
Quick answer: for most tourists visiting Greece for one week, a plan with 5–10 GB is more than enough. Travelers spending two weeks island hopping or working remotely may prefer 10–20 GB or an unlimited plan.
