Does a travel eSIM make calls and texts, or give you a number?
A travel eSIM from yesiim is data-only, which means it does not give you a new phone number and cannot place regular voice calls or send standard SMS. It provides mobile internet for your trip, and you make calls or send messages through apps like WhatsApp, FaceTime, or Telegram over that data. Keep your usual SIM if you also need your normal number to stay reachable.
What data-only means
A yesiim eSIM connects your phone to a local mobile network for internet access only. There is no phone number attached to it, so features that depend on a number, such as traditional phone calls, standard text messages, and codes sent by SMS, will not run through the eSIM. Everything you do happens over the data connection instead.
How to call and text on a data-only eSIM
- Turn on the yesiim eSIM and confirm you have a working data connection.
- Open a messaging or calling app such as WhatsApp, Telegram, FaceTime, Signal, or Messenger.
- Call or message contacts who use the same app; the audio, video, and text travel over your data, not over a phone line.
- For calls to landlines or non-app numbers, use an internet calling service that gives you credit or a virtual number.
Keeping your own phone number
If you need your regular number to receive calls, texts, or SMS verification codes, keep your home SIM in the phone alongside the eSIM. On a dual-SIM device you can set the eSIM for data and leave your physical SIM active for your number, usually with roaming for calls and SMS turned off to avoid charges. That way your contacts still reach you on your usual number while you browse on the eSIM.
