LONDON (AP) -- Skype is dead. What now?

Microsoft's shutdown of Skype on May 5 sent millions of users scrambling to find an alternative to the pioneering internet phone service.

Skype, which Microsoft bought in 2011, was beloved by a dwindling group of users who appreciated how it let them make cheap long-distance calls as well as communicate with other users through chat messages, voice or video calls.

Some liked its simplicity and ease of use -- an advantage, for example, when setting up a communications app for an elderly parent living far away.

Or they just used it out of habit.

Skype was founded in 2003 and was among the first in a wave of communication services that used voice over internet protocol technology (VoIP), which converts audio into a digital signal.

Skype's disappearance also inconveniences Americans and other expatriates living overseas who signed up because they needed an U.S.-based number to receive text authentication codes from, say, a bank back home. It was also handy for calling 800 numbers for free even if you weren't living in North America.

Here is a guide for life after Skype:

Microsoft announced in late February that it was shutting down Skype on May 5 and shifting some of its services to Microsoft Teams, its flagship office videoconferencing and group collaboration platform.

Skype users can use their existing accounts to log into Teams and have the option to automatically migrate their contacts and chats.

If you had a Skype number or a calling subscription, it stopped automatically renewing on April 3.

If your account still has credit, you can access Skype's dial pad from the web portal or Teams to make calls.

Skype numbers won't immediately expire on May 5 so you'll still be able to receive calls until your subscription expires. But you'll have to use Teams or keep the Skype dial pad open on the web portal to receive them.

If your Skype number hasn't expired and you don't want to lose it, you should transfer it to another provider.

Skype numbers can be ported to a phone carrier or any number of other VoIP services. But you'll have to start the process through the new provider, not Skype.

Google users can access the online search giant's internet phone service to make calls from a smartphone or a desktop web browser. You can get your own Google Voice phone number and use features like call forwarding and voicemail. Or you can port your number from another service like Skype, but it will cost $20.

Calls to U.S., Canadian or Puerto Rican numbers are free. Rates for other countries vary.

The free version of Google Voice is only available to U.S. residents physically located in the 48 contiguous states, so that means expatriate Americans can only use it if they registered before they moved overseas.

"You cannot sign up for a Google Voice number while outside the USA," according to a help page. "Do not try to circumvent this by using a VPN."

Owned by Japan's Rakuten, Viber was long considered one of the closest competitors to Skype. One key difference is that Skype users don't need a phone number and are identified by their usernames, while Viber users need a number to register for service.

Similar to Skype, Viber users can buy credit or packages to call phone numbers around the world but it's no longer possible to get a Viber number to receive calls.

The videoconferencing service that's become a byword for online company meetings offers a calling service, Zoom Phone, and features like number porting and the ability to send and receive SMS text messages.

Take note that Zoom Phone isn't free. There are various calling plans that involve a monthly subscription cost and extra fees for international calls.

Microsoft users have the option of making calls on Teams, dubbed Teams Phone. Like Zoom Phone, you'll need to buy a subscription and pay extra for international calls.

But it's not an option for regular people because Microsoft says Teams Phone isn't for consumer use and is only available to small and medium-sized businesses.

If you absolutely need a U.S. number but live overseas, sign up for service with a low-cost virtual wireless carrier that offers cheap cellphone plans or pay-as-you-go rates.

One provider, Tello, offers monthly plans for as little as $5 and says users can activate its service even if they're living outside the U.S.

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.

They offer cheap data access rates so you can use the internet without worrying about racking up a huge bill when you get home.

Unfortunately, you can't port a Skype number to an international eSIM because of "the fundamental differences" between VoIP services and traditional mobile networks, said Pedro Maiquez, co-founder of eSIM provider Holafly. "Skype numbers are not tied to a mobile carrier's physical infrastructure, making them incompatible with mobile eSIM solutions."
