eSIM vs Roaming Plans — Real Cost Comparison
International roaming can cost {price.5}–{price.15} per megabyte with some carriers. A single hour of video streaming could cost {price.500} or more in roaming fees. Here is an honest, numbers-first comparison of eSIM plans vs every roaming alternative.
The true cost of carrier roaming
Home carrier international data charges vary widely:
| Carrier type | Pay-as-you-go rate | Notes |
|---|---|---|
| US carrier (T-Mobile, AT&T, Verizon) roaming | 0,01 €–13,80 € per MB | Varies by destination country |
| UK carrier (EE, Vodafone, O2) zone 1 | £0.002–£10 per MB | 'Zone 1' countries cheapest |
| Carrier international add-on package | 9,20 €–18,40 €/day or 46,00 €–92,00 €/week | Often throttled to 256 kbps |
| EU roaming (within EU/EEA) | Free at home rates | Genuine exception — no extra charge |
At 9,20 €/MB, a 1 GB video stream costs 9.200,00 € Even 'day pass' add-ons at 9,20 €/day throttle to 256 kbps — barely enough for maps.
