Roamify

Roamify competes on price, starting at $2 per gigabyte for pay-as-you-go plans, with unlimited data tiers available for longer stays. The service supports dual SIM functionality, so you can keep your home number active while using Roamify for data and local calls. This flexibility appeals to business travelers and anyone who needs to maintain both a domestic and travel presence simultaneously.

Since its 2019 launch, Roamify has built a lean operation that keeps costs low without sacrificing essential features. The per-GB pricing model works well if you know roughly how much data you'll consume and want to avoid overpaying for data you won't use. Their unlimited plans offer good value for travelers staying two weeks or longer.
