Which one to pick
Each of these is the better buy for someone. Ours included, honestly.
Who each of the 6 is best for
Pick Inbox eSIM if
- You want no app and no account: the QR and a one-tap install link come by email.
- You want a fixed price you can see before you fly (5 GB for 30 days: $4.90).
- You may cancel: unused and never installed, the money goes back to your card.
Pick Holafly if
- You stream or work heavily on your phone for a set number of days and do not want to track GB at all.
- You book far ahead: an unactivated Holafly eSIM can be refunded up to 6 months after purchase (ours: 30 days).
- You travel every month and want one subscription that renews, with a local number for incoming SMS.
Pick Ubigi if
- You want data on a Windows laptop or tablet: Ubigi supports Windows 10 and 11 and ships inside some laptops.
- You travel often and want a monthly or annual plan that renews on one long-lived eSIM.
- You use a lot of data: its unlimited plans keep full speed up to 15 to 60 GB, then drop to 2 Mbps.
Pick Nomad if
- You need a local phone number in Thailand or a UK/Maldives calling plan, which Nomad sells.
- You are new to eSIMs and want to try one first: Nomad offers new users a free 1 GB trial eSIM.
- You travel often and want the Nomad Pass: one eSIM, 1 GB backup data each cycle and 15% off add-ons.
Pick Jetpac if
- You fly often: SmartDelay gives free airport lounge access when a registered flight is delayed.
- You need to make phone calls: Jetpac sells outgoing-call voice packs; we sell data only.
- You want WhatsApp, Maps, Uber and Grab to keep working after your data runs out (packs of 3 GB and up).
Pick Yesim if
- You travel several times a year: the Unlim Day Pass days stay valid for 365 days and are used only on days you go online, in 83 countries.
- You would rather pay for the MB you use than pick a plan size (Pay & Fly).
- You need a separate number to receive SMS codes for an app (sold as a virtual number).
