Important news about VoIP services for business
2024. Microsoft updated Skype and removed all ads
Microsoft still believes in Skype and says it's used by millions of people each month for chats, calls and video calls. The recent update improves reliability and performance across various platforms. It also resolves permission issue on iPad, fixes button alignment in the Calls tab on Mac, eliminates large spaces between contacts in compact mode on Mobile, removes call option visibility from the Copilot chat on iOS, corrects market selection for channel mute/unmute actions. Besides, Microsoft removed all ads from Skype. But it doesn't mean that Skype is now non-profit. It still earns on cheap international voip calls and local numbers.
2020. Facebook launches CatchUp, an audio-only calling app
Facebook launched an app CatchUp that's basically Houseparty for phone calls (not video calls). CatchUp, which is free to download, lets users see who's available to voice chat, and then allows them to initiate both one-on-one and group calls within the app. CatchUp is a standalone app that is not connected with the Facebook app. You don't have to have a Facebook account, or an account with another Facebook-owned company, to use it. Since it's part of Facebook's "experimental" division, it's a bit soon to tell how it could play into the business, presuming the app sees any success.
2020. Truphone raises $38M at $516M valuation for its eSIM business
Truphone, a UK-based startup that provides voice and data services for phones, tablets and IoT hardware by way of eSIM software integrated directly into the devices, has raised $38 million. The company said it has now provisioned some 4 million eSIM profiles globally and is seeing further eSIM downloads of 20,000 daily. Although eSIM technology was conceived as a quick way to switch carriers without physically changing fiddly, tiny physical cards (and subsequent carrier contracts), it’s an interesting datapoint right now, given that we are seeing a big focus on technology and transactions that can be run in a contactless way (thus avoiding the spread of the novel coronavirus).
