Because mobile virtual network operators like Tello are essentially wireless phone companies that piggyback off a bigger carrier’s physical network, you can’t use it to make calls on a computer or an app.There are a slew of Skype pretenders offering phone calls over the internet, such as Zoiper, VoIP.ms, CallCentric, Mytello, and Virtual Landline. Many are aimed at business users.

Some are capitalizing on Skype’s disappearance. Hushed, which started as an anonymous calling app, bills itself as a Skype alternative. Users can buy a phone number from the U.S., Canada, the United Kingdom or Puerto Rico or port their own number.It warns that some of its numbers aren’t guaranteed to work with third-party verification text messages.“We do not intentionally block anyone from receiving these codes, but it’s common that some services will prevent verification texts from being sent to certain phone numbers due to their own security policies,” Hushed says on its website.

Maybe you can’t decide which calling service you want to switch to. If you want to save your current number, there are services to just park your number like NumberBarn.com and Parkmyphone.com.They let you store a phone number for a monthly fee while relaying any text messages sent to that number. You can port the number to another service whenever you want.

Beware, you can only port in U.S. or Canadian phone numbers.

What about an international eSIM? They’re the virtual version of the mobile phone SIM card that you can buy and add to your phone when you’re on a trip to save on roaming fees.CHARLOTTE, N.C (AP) — Patrick Agyemang scored two goals in a span of five minutes and Pep Biel scored the game winner and Charlotte FC beat the Columbus Crew 3-2 on Saturday night
