A call comes in
When nobody is free, the voice agent answers.
What Phonestar does
Your German number in the app, a phone system for teams and a voice agent that answers. Here is everything in detail.
Extensions and users
Everyone on the team gets an extension with its own short number and makes calls with it in the app. In the portal you decide who has which extension, number and role.
One user in Start, four in Business, in Business each further one €19.00 a month.
Phone numbers
One German mobile number is included in every plan, new or brought along; porting is free. Local landline numbers and numbers in 45 further countries are set up by our support team.
Each further number €2.99 a month.
Groups
Several extensions ring together under one short number: all at once, one after another or building up. Every member switches themselves on and off in the app.
Included in the Business plan.
Calls in the app
Phonestar Connect for iOS and Android makes calls over Wi-Fi or data, with your German number as caller ID. Mailbox messages arrive as a chat in the app.
Set up with the QR code from the welcome email.
Texts and TANs
Receive and reply to texts in the app, with your German number as sender; bank TANs arrive reliably. A data connection is enough; you do not need a German SIM card.
Reply with your German number once a sender number is assigned to your extension.
Office hours, forwarding, mailbox
For each number you decide where calls go during office hours, outside them and on public holidays, plus a “Closed now” switch. If nobody answers, the mailbox takes over; the message arrives in the app and by email if you like.
Announcements by typing text from the Business plan.
The voice agent
It picks up when nobody else can — and afterwards you read what the call was about.
-
-
Conversation
It asks what the call is about and notes everything.
-
Report
Summary and transcript arrive by email and are in the portal.
The voice agent greets callers with a note that it is an AI, handles the call and sends you a transcript and summary. You set greeting, voice and transfer in the portal.
Business includes one voice agent with 100 minutes per month; each further one costs €49.00. It is not available on Start.
Listen for yourself
All three voices read the same text — exactly as your callers would hear it.
- Ramona Warm and friendly — for reception and appointments
- Vito Matter-of-fact and professional — for sales and support
- René Natural and calm — pleasant on longer calls
„Welcome to Phonestar. For sales, please press one; for customer service, press two. We will connect you to the next available colleague."
Fax arrives as email
A fax to your fax number lands in your inbox as a PDF and stays in the portal for 90 days. Bookable in both plans; receiving faxes, not sending.
Call list and customer portal
In the customer portal you see every call with duration and price, set a monthly cost limit and download the itemised bill as CSV. Numbers, extensions, invoices and eSIMs are managed in the same place.
One login for account, phone system and eSIMs.
eSIM for your team
Staff on business trips, abroad or spread across locations get data packages from the portal, assigned per extension, including for temporary use in Germany. They cost the same as in the shop.
Buy in the portal or in the app, per extension.
Destinations and pricesThe difference
What a parked prepaid card and roaming cannot do.
Your number stays
- The number belongs to your contract, not to top-ups or a SIM card.
- You bring your existing number free of charge, landline or mobile.
- Landline numbers usually take two to four weeks from the signed form; for mobile numbers we file one application per number.
- One German mobile number is included in every plan; each further number costs €2.99 a month.
- Local landline numbers require a location in that area and proof of address; numbers in 45 further countries are set up by support.
Abroad without roaming
- Calls run encrypted over Wi-Fi or your local data plan.
- People see your German number; anyone calling you from Germany pays for a domestic call.
- Texts and TANs arrive in the app, and you reply to texts with your German number as sender.
- No location check and no time limit abroad, even after years.
- Cancel monthly, no setup fee, no hardware.
What it is built for
Four situations where a phone system in the app makes the difference.
-
Trades and crafts
No landline rings on a roof. Calls reach the phone you carry anyway — showing your company number.
-
Medical practice
The voice agent greets callers, puts them through to reception or takes a message when nobody is free. After closing time the office hours take over.
-
Law firm
One direct-dial number per lawyer, a group for the front desk and an announcement that fits the firm.
-
Distributed team
Four time zones, one set of German office hours. Routing follows Germany, not where somebody happens to be.
Frequently asked questions
The uncomfortable ones first.
Not through your Phonestar number. Dial emergency services over your phone's mobile network: 110 or 112 in the device's phone app via your SIM card, and your mobile operator passes your location to the control centre. Through our app we cannot tell where you are, so we do not route emergency calls through our network; anyone who tries anyway hears an announcement from us.
Yes. Your Phonestar number is a real German mobile number, not a landline or special-rate number. Texts to that number land in the app wherever you are: codes from banks, payment services, government portals and online accounts, as well as personal messages. Whether a particular service sends texts to your number is up to that service.
Nothing. The four-month rule concerns roaming on mobile contracts within the EU. Phonestar calls run over data, and our system checks neither where you are nor how long you have been away. Your plan stays the same whether you are abroad for four weeks or four years.
Not for your German number: it lives in the app, not on a SIM card. The app only needs a data connection — Wi-Fi, the SIM from the country you live in, or mobile data booked as an eSIM in the same app. You still make emergency calls through the SIM card in your phone.
Yes. Calls with Phonestar Connect run over any data connection, including the mobile data of an eSIM bought from Phonestar. Abroad, that makes you independent of Wi-Fi and a local SIM. There are no roaming charges, because the call is routed through our server in Germany into the German network; the eSIM only carries the data, and all it uses is data volume.
Without data there is no call — that is true of every system of this kind. On a phone the app uses the mobile network as soon as Wi-Fi is missing. For incoming calls you set a destination per number in the portal, for office hours, outside them and on public holidays; we recommend voicemail or a voice agent there.
Yes, and it costs nothing: we charge no fee for porting a number, neither for landline nor for mobile numbers. Landline numbers usually take two to four weeks from the signed form. For mobile numbers we file one application per number.
One month. You pay one month in advance and can cancel to the end of the current calendar month. We do not offer 24 or 60 month contracts.
No. We offer neither a trial period nor test numbers. The shortest way to try us out is one month of Start at the price on the price list — after that you can cancel to the end of the month.
Yes. Texts to your German mobile number arrive in Phonestar Connect, and you reply in the app with your German number as sender. Sending requires a sender number assigned to your extension. Texts are not shown in the portal.
Yes. Book a fax inbox in the portal for €4.95 a month and assign one or more of your numbers to it — those numbers are then reserved for fax only. Faxes to them arrive as PDF by e-mail at up to five addresses and stay available in the portal for 90 days. We do not offer outbound fax at the moment.
So that the subscriber details we collect under telecommunications law are correct (name, address and, for individuals, date of birth), and so that nobody misuses phone numbers. Before we activate your service, we therefore check your details for plausibility; we ask for an ID document only in individual cases. For local landline numbers we also need proof of address.
On servers in the European Union. Summaries of voice agent calls are produced by a provider that processes within the EU. We do not store audio recordings of calls; call reports are deleted after 90 days. Which service provider plays which role is set out in the privacy policy.
No emergency calls. No wall board for team leads, no three-way calling, no screen sharing — we deliberately did not build those. No video conferencing either, and no Microsoft Teams integration. There is currently no classic voice menu and no call queue; on Business the voice agent greets callers and puts them through instead. You can receive text messages, but not send them. Local numbers and international numbers are set up by our support team rather than left to self-service.
