Yesim review: pay-as-you-go data and virtual phone numbers
Yesim offers both fixed data bundles and pay-as-you-go credit you can spend gradually, plus optional virtual phone numbers for SMS verification. It's a good fit for unpredictable trip lengths or anyone who wants a local-feeling number without a physical SIM.
Yesim is a newer name than Airalo or Holafly, and the pay-as-you-go model is genuinely the reason to consider it over the bigger names.
The pay-as-you-go model
This is the standout feature. Instead of committing to a fixed data amount, you load credit and spend it as you go — useful if your trip length or data needs are uncertain, since you’re not stuck either buying a second plan or overpaying upfront.
Virtual phone numbers
A less common feature: Yesim offers virtual numbers that can receive SMS, which is handy for verification codes on apps or accounts you need while traveling. It’s not a full local number for calls, but it solves a specific annoyance most eSIM providers don’t address at all.
Where it’s less proven
Yesim is smaller and newer than Airalo or Holafly, so there’s less of a long track record to point to, and coverage in less-visited countries can be thinner. For mainstream destinations it performs fine in my experience.
Who should use Yesim
Travelers with an uncertain trip length, anyone who wants to avoid buying data in large fixed chunks, or anyone who specifically needs SMS verification while abroad.

Frequently asked questions
What's the difference between Yesim's pay-as-you-go and fixed plans?
Fixed plans work like most competitors — buy a set data amount for a set price. Pay-as-you-go lets you load credit and draw it down as you use data, which suits trips where you don't know exactly how much data you'll need in advance.
What is a virtual phone number used for?
Yesim's virtual numbers are mainly useful for receiving SMS verification codes (for apps, bank logins, or two-factor authentication) without needing a local physical SIM — they're not a full replacement for a local calling number.
Is Yesim reliable for longer trips?
It works well for longer or unpredictable-length trips specifically because of the pay-as-you-go option, which avoids either running out of data on a fixed plan or overpaying for data you don't use.
