What roaming actually costs in 2026
Three carriers, three different ways to charge you too much.
Charged any day your phone registers on a foreign network — including background app syncs. No daily cap. 2GB at high speed, then at reduced speed.
Free tier is capped at 128kbps — 2G speeds. Adequate for text. Useless for navigation or photos. Go5G Plus includes 5GB high-speed free. $10/day International Pass unlocks full LTE.
5GB at LTE, then drops to 3G. Auto-enrolls unless you opt out. One background notification on day one: $12 charged.
The 7-day trip cost breakdown
Same trip, same data, three carriers vs a travel eSIM.
| Option | Daily Rate | 3 Days | 7 Days | 14 Days |
|---|---|---|---|---|
| AT&T Day Pass | $12 | $36 | $84 | $168 |
| Verizon TravelPass | $12 | $36 | $84 | $168 |
| T-Mobile Intl Pass | $10 | $30 | $70 | $140 |
| Travel eSIM | $1.29 | $9 | $9–$18 | $9–$18 |
Travel eSIM price is fixed per plan — not per day. 14-day trip costs the same as 7-day if data lasts.
Why an eSIM saves 80%+ over your carrier
Carriers charge per day because they can. There is no technical reason international data should cost $12/day — local SIM cards in Europe sell for $1–$2/day wholesale. Your carrier marks up that cost by 600–1,400% and calls it a “Day Pass.”
A travel eSIM buys that same local access directly. eSIM providers connect to the same European networks AT&T uses — Orange, Deutsche Telekom, Vodafone — but charge you the wholesale rate, not the retail markup. The data is identical. The network is identical. The price is not.
For a 7-day Europe trip: AT&T charges $84. A travel eSIM costs $9. That is an 89% reduction on a single trip. A 14-day trip widens the gap further — the eSIM price stays flat while the carrier bill doubles.
