Your questions
Answered from our data.
Is there a free eSIM?
Not for a whole trip, as far as we found; but trials give 100 MB to 1 GB with no credit card, and carriers give 10 GB for 24 hours on arrival in the UAE and Vietnam.
Which eSIM has a free trial?
With no credit card: Nomad, GoMoWorld, GigSky, Eskimo, Airhub, Roamless, My Truphone, and Ubigi. With a card required at checkout: Keepgo.
Can I get a free eSIM on arrival?
Yes, in a few countries: du and e& in the United Arab Emirates (10 GB for 24 hours), MobiFone in Vietnam (10 GB for 24 hours, one per passport).
Do T-Mobile or Verizon trials work for a tourist?
They are designed for residents: AT&T requires you to live in the US, Verizon and Visible require you to be there; T-Mobile, Verizon and Visible do not say whether a foreign number is accepted.
Is a free eSIM enough for a trip?
Rarely: trials give a small allowance or a short validity; they are for testing the network before you buy.
Do I need a card for a trial?
Not with Nomad, GoMoWorld, GigSky, Eskimo, Airhub, Roamless, My Truphone, and Ubigi; other providers ask for a card, even for a trial.
Which eSIM to pay for if the trial is not enough?
For a week of everyday use (6 GB), the eSIMs we compare start at $8.00 depending on the destination.
Does a free trial commit me to buy?
Not with the providers we checked: the trial simply ends; just make sure no renewal is switched on.
