Saily: Not confirmed yet
Maya Mobile: Not confirmed yet
Refund policy
GigSky: SIMs and top-ups can't be returned once sold and unused data isn't refunded; a minimally used subscription plan (under 1GB) affected by a connectivity issue may be refunded at GigSky's discretion.
Ubigi: Refunds only for unused plans — a plan can't be refunded once you start using it. Requests within 14 business days of purchase, processed within 10 business days to the original payment method.
Saily: Full refund if the eSIM has not been installed or the data plan was never activated; after activation, refunds only while more than 99% of the data balance remains unused (subscriptions: within 14 days).
Maya Mobile: Full refund (less processing fees) within 30 days if no data has been used — including incompatible or carrier-locked devices; partial refunds proportionate to unused data for Maya-side network issues.
Validity starts
GigSky: Plans are turned on by the customer when ready to travel, not automatically at purchase, per GigSky's setup flow ('Activate When You Travel, Top Up Anytime').
Ubigi: Smartstart: the plan's validity countdown begins when you first connect at your destination, not at the moment of purchase. Preloaded eSIM QR codes must be redeemed within 6 months of purchase or they expire unused.
Saily: Saily plans must be installed before your trip; the validity/data countdown starts when the eSIM activates (first connection at your destination), not at purchase.
Maya Mobile: Each plan runs for its full duration once activated in the app (turn the eSIM on when you land, not automatically at purchase); you're charged once at purchase regardless of how much data you use, and there are no partial refunds for unused days.
Fair-use limit
GigSky: On Unlimited plans, GigSky may reduce speed during a single day of very heavy use (e.g. video streaming); normal speed resumes the next day. No specific data threshold or throttled speed is disclosed.
Ubigi: Unlimited plans run at full speed up to a threshold, then drop to 2 Mbps: about 15–25 GB on 7-day country plans and 60 GB on 30-day regional plans, depending on the destination.
Saily: Unlimited plans include a Fair Use Policy: full-speed data resets every 24 hours (5GB standard, as low as 3GB in some countries), then speed is reduced until the next reset.
Maya Mobile: Unlimited plans: speed may be temporarily throttled to 10 Mbps once daily usage exceeds 3GB, and to 1 Mbps if very high usage continues; any throttle is removed within 24 hours. Prepaid (fixed-GB) plans run at full local network speed.
Top-ups & rollover
GigSky: Eligible plans can be topped up anytime in the GigSky app (My Plans > Top Up), with the data added to the existing plan; not every plan supports top-ups and complimentary Visa plans can't be topped up.
Ubigi: Existing Ubigi eSIMs can be recharged with a new data plan directly through the Ubigi app or ubigi.me account — even without Wi-Fi or remaining data — without installing a new eSIM.
Saily: Existing Saily eSIMs can be topped up (including an Auto Top-Up option) directly in the Saily app without reinstalling, per their Help Center.
Maya Mobile: Add data to an existing eSIM any time: pick a package in the Shop and choose your existing eSIM at checkout (no reinstall); optional Auto Renew also extends 30-day plans monthly.
