AlterPhone: Numbers & eSIMs

AlterPhone is two essentials in one app: a second phone number for calls, and travel eSIMs for mobile data in 200+ countries. No second SIM, no carrier hopping, no surprise roaming bills.

SECOND PHONE NUMBER
• Real second number — make and receive calls
• Pay-as-you-go credits, no monthly contract
• International calling at competitive rates
• Keep your primary number private — useful for work, travel, dating, classifieds

TRAVEL eSIMs
• Buy mobile data plans for 200+ countries and regions
• Activate instantly via QR — no physical SIM swap
• Single-country, regional, and global plans
• Top up anytime if you run out
• Powered by trusted providers, sold at clear, all-in prices

WHY ALTERPHONE
• One app for calling and data — manage both from a single wallet
• No subscriptions — buy credits or data only when you need them
• Privacy-first — we don't sell your data
• Cleaner pricing than carrier roaming

HOW IT WORKS
1. Sign in and pick a number, or browse eSIMs by destination
2. Top up credits or buy a data plan
3. Call or roam — all in one app

CREDITS & DATA
Credits are consumable in-app purchases that never expire. Outbound calls deduct credits per minute at rates shown before each call. eSIM plans are one-time purchases delivered via QR code; data is metered per the plan you buy.
