imo calls run over the internet between imo users, using the phone number your imo account was registered with. Both people need imo and a data connection.
imo is a messaging app that uses your phone number as your account. Voice and video calls go over Wi-Fi or mobile data to other imo users, so there is no per-minute charge from imo for these calls. Your mobile plan's data charges still apply.
| Person | Can call you on imo? |
|---|---|
| Contacts who have your number and use imo | Yes |
| People in imo groups you share | Possibly, depending on privacy settings |
| Someone without imo | No, they must install imo |
imo calls show the caller's imo profile, which is linked to the phone number used at sign-up. Calls do not come through the phone network, so your carrier's caller ID settings, such as hiding your number, do not apply to them.
imo's main calls are between imo users. If you need to call a landline or a phone without imo, use a normal phone call or a service built for calling regular numbers.
If you change phone numbers, use imo's option to change the number in settings while you still have the old SIM, so your contacts and chats move with you. See imo recovery if the old number is already gone.
Verification problems? See imo code not received.
imo supports group voice and video calls with several people at once. Everyone needs imo and a connection, and call quality follows the weakest link in the group, so ask people with poor signal to switch to voice only.
Yes between imo users, apart from your data costs.
imo calls are mainly between imo users.
No, imo calls do not use the phone network.
