Plans with international calling are too rich for my blood, I prefer to buy the Groundwire app (10.-) and call using my data and VoIP. It also is much cheaper when roaming as you only need roaming data. I use VoIP.ms and it’s pretty good for US and Canada calls (1/2 cent a minute) but they’re not so good for EU rates.
What’s the VoIP.ms of Europe?
I use JustVoip (combined with its mobile App, MobileVoip) and it used to work pretty well to me. I say it “it used to work” because since 2 years I changed jobs and theoretically need to be available 24/7, with clients all around the world, so my employer pays the phone bill (calls and data) without asking questions (they have a deal with Swisscom), so I haven’t used Justvoip that much lately.
Thanks, I’ve used Dellmont’s many many many resellers in the past but always found the call quality lacking and there were always issues with caller id. glad to hear you didn’t have issues with them but I’m hesitant to use them again.
Hi folks, slightly OT… do you get a phone nr. where you can receive SMS/2FA with these providers?
I’m having the opposite problem of needing to keep “alive” two foreign phone numbers without any use, just for banking authentication… and it’s really an hassle.
Thanks!
VoIP.ms lets you port existing DIDs and keep them for a low monthly fee. But I don’t think they do every country in the world, just a select few. Otherwise twilio can most likely do what you need but I don’t know how much it costs and if it makes sense in your situation.
I just bumped into this discussion. Several years ago, I used Voip Buster… It an old online voip service. From Switzerland for most of Europe’s landlines is 0,017 - 0,022 eur / minute.
You can check their rates here.
It’s so old that their mobile app and webpage could really use a refresh…
Very recently I needed to use it again and it still works. My 12y old ‘credit’ was still there 
EDIT: whenever you buy credit (i.e. 10 euros), you get 120 days free-to-use (check list of countries) before starting the billing on that credit.
Voipbuster is yet another Betamax if I remember correctly. A testament to Betamax’ ubiquity and dependability if anything.
Hi Everyone,
I occasionally need to call international numbers (mostly EU, mobile) in Switzerland, but outside of Switzerland too (while travelling in the EU). I have unlimited data from Yallo everywhere (in CH, EU & USA), so I thought to search for a reliable VoIP mobile application for my international calls.
So far I used ViberOut, and they charge around 0,15$ per Minute for mobile calls. I just recognized, they have a subscription for World (6,5 CHF / month) with unlimited calls (mobile & landline) for 60 countries (EU incl.).
Do you have any better option or idea to keep VoIP calls in CH and abroad for the lowest costs? One important feature: the caller can see my registered real Swiss mobile phone number (+4176XXXXXX).
Thanks,
Mr.Paprika 
When I was working in Bahrain, Skype had pretty good rates for on the minute calls and was always working really well. If I remember well, you could even get a separate phone number from where people could call on your skype account (not sure though).
Might be an alternative.
I use Skype, but not sure about the caller seeing your registered mobile phone piece.
I just use stuntcalls, the price is very low - check on the website, it depends on the country, landline and mobile you’re calling.
It allows you to call with your own number via an app and all you need is mobile data or Wi-Fi.
reviving this threat, as a major player, Skype, no longer exists. I used it for years, with easy prepaid handling, no subscription required, ideal for the occasional call outside of one’s flat abo
I checked out voipvoip.com, advertizing
however i didnt read the details and ended up with $0.4/min or so from Switzerland (= from on-EU…) so not my go-to service.
any current recommendations?
I used Keepcalling a couple of times since Skype does not exist anymore. Didn’t reserach much for alternatives but seems to work well so far.
I don’t like to install apps, that was great with Skype. Is there a company where you can call from your computer without installing an app?
If you are willing to pay for it (not having to install apps), I’d try teams in the browser with a calling plan (see link below for details)
I was moved from Skype to teams, but lost my subscription money. All the plans are very expensive and seem not to include landline phones. $10 a month, I did use $10 in 10 years on Skype…
Skype was dead the moment Microsoft bought it…
You should still be able to use your credits
From Skype is retiring in May 2025: What you need to know - Microsoft Support
Can I use my Skype credit?
Skype Credits can be used for calling. Automatic top up services are no longer be available. The Skype Dial Pad is available to remaining paid users from the Skype web portal and within Teams Free, where you will continue to be able to use your subscription or Skype Credits
Seems to be available only in the app. On the web page of teams I can find my chats and contact, but no credit and no dial pad. Only a link to very expensive voip subscription.
Anyhow, the credit was 12 years old, most people that I could only reach by landline are dead now. But not all…
I think I just use my landline, not worth the trouble.
OK, found it, it is still under “skype.com”. Could reactivate my credit and can still call from the skype page.
Thanks for the tip!!!
Worked this morning, doesn’t work now. It says “please register your skype ID” and klicking on the provided link tries to open a page “https://pdwumurphy.azurewebsites.net/” which does not exist apparently.
Typical Microsoft experience… This morning I could call a phone with my skype credit on https://calling.web.skype.com
Addendum: works again, seems to have been a temporary problem. I will use it until the rest of my money is spent… probably another 10 years.
