No SIM means no dial tone — usually
Data-only eSIMs (common for travel), tablets, and Wi-Fi-only devices can browse and message fine but have no way to place a real phone call — messaging apps only reach people who also have the same app installed. Hyallo doesn't need a SIM at all: it places the call over your internet connection and reaches an ordinary phone number on the other end.
How it works
Wi-Fi, a data-only eSIM, or a mobile data plan all work equally well — Hyallo never touches your carrier's voice network.
Signing up needs only an email — you don't need a phone number to start calling one.
Tablet, laptop, or an old phone kept only for Wi-Fi — if it has a browser and a microphone, it can call.
Call without a SIM
Any internet connection is enough.
Just an email — no phone number needed to create the account.
A landline or mobile, anywhere, with its country code.
Who this is for — and the one limit
This fits anyone on a device that has data but no voice line: travelers on a data-only eSIM, students with a tablet and no local plan yet, or anyone whose phone plan simply doesn't include calling minutes. The one thing it does not do is give you an incoming number — Hyallo is for placing calls out, not receiving them, and it does not send or receive SMS.
What it costs
Real per-minute rates, in your currency — no plans, no bundles.
Frequently asked questions
Can people call me back on Hyallo?
No — Hyallo makes outbound calls only. It does not give you a phone number to receive incoming calls or texts.
Does this work with a data-only eSIM?
Yes — Hyallo only needs a data connection, so a travel eSIM with no voice plan is exactly the use case it covers.
Do I need a phone number to sign up?
No — an email address is all that's required. You can optionally verify a number later to use as your caller ID.
