✨ Why AlterPhone

Privacy first — give out an AlterPhone number instead of your personal one

One app for travel — local phone number abroad and mobile data, in the same place

Fair pricing — pay only for what you actually use on calls; eSIMs priced to save you money vs. airport SIMs and hotel Wi-Fi

Secure — encrypted signalling, verified webhooks, strict data handling

No surprises — every price shown before you pay, every plan renewable or cancellable on your terms

Perfect for:

- Frequent travelers and digital nomads

- Freelancers and small businesses needing a dedicated work line

- Online sellers, hosts, and dating-app users who don't want to expose their real number

- International calls to family and friends abroad

- Anyone who needs a phone number for SMS verification without giving up their primary

Please note:

Phone numbers are subject to availability. Carriers and regulators can change which countries, number types, and area codes are offered at any time, and specific numbers may be unavailable even when a country is listed. If a country you need isn't shown in the app, it's currently out of stock with our carrier partners — please check back later.
