Roamer Labs Inc

About this app

Roamer is a roaming-free internet tool built for cross-border travelers. Avoid expensive roaming charges, frequent SIM swaps, local SIM queues, pocket Wi-Fi rental, and buying a new data plan for every trip.

— Scenario 1: Phones with native eSIM support —
Roamer hosts the world's largest eSIM marketplace.

No need to shop around. Roamer covers 180+ countries and regions with dozens of local providers in many destinations, giving you far more plan choices than typical eSIM apps. The AI smart filter helps match low prices quickly, saving time and money on travel data.

• Full in-app operation: activation QR codes, setup guides, and one-tap activation. No email attachments or complicated steps.
• Fast connection: buy and activate before boarding, then connect when you land. No physical SIM or store visit.
• Budget-friendly plans: from $0.68 for 500MB per day.
• Flexible validity: 1-30 day short plans, plus 60/90 day, half-year, and annual options.
• Data choices: from 500MB to unlimited data.
• Wide coverage: 180+ countries and regions.
• Access without VPN: full app functionality in China and eligible regions with no VPN required.
• Foreign phone numbers: get an overseas number to receive calls and SMS.
• Transparent rewards: invite friends for discount coupons with visible progress and no hidden tricks.

— Scenario 2: Phones without native eSIM support —
No need to buy a new phone. Purchase a Roamer writable SIM in the app to unlock eSIM-style flexibility on Android devices.

• One-tap writing: rewrite eSIM plans for 180+ countries. Insert the card and the app auto-detects it.
• Reusable value: buy once, reuse for future trips, and top up data only when needed.
• Less travel hassle: no messy SIM storage, constant card swaps, lost SIMs, or forgotten PINs.
• Broad compatibility: after writing an eSIM profile, the SIM can work with iPhone, iPad, Android phones, tablets, laptops, and smart devices with SIM slots.
• Freedom of choice: write supported eSIM profiles from other vendors to the card, instead of being locked into one source.

The Roamer writable SIM supports unlimited rewriting and switching of global eSIM profiles after a single purchase. One card can replace piles of local SIMs for easier global travel.

— More than international data —
Roamer also offers low-cost international calling from $0.025 per minute. Your account balance never expires, helping you stay connected with family, friends, and clients abroad.

Whether your phone supports eSIM or not, Roamer delivers simple, low-cost global internet solutions for international travel.

— Privacy & Data Control —
Users may export or delete personal data in the app at any time. Roamer is designed with GDPR compliance in mind.

— Device Compatibility —
Roamer writable SIM works with Android smartphones.

Quick eSIM check: dial *#06# on your phone. If an EID appears, your device has native eSIM support. If no EID appears, use a Roamer writable SIM.

— Language Support —
22 built-in languages for users worldwide.

Ratings and reviews

The frustrating part is adding on credits and money gets deducted but credits won't reflect to your account. I still can't make calls the stupid app keeps sending me back to adding credits. A TRUE SCAM!!!!!!!

Horrible so far. Thought this should be authentic because of Daily mail UK coverage. I have tried consistently for over a year and still dont to Nigeria from UK. And you pay monthly for non functioning app? It overpromises and underperforms. Finally i deleted and moved voicemail to Hullomail. Is this a scam or is it me missing something?

Installed roamer, still have money in account, did not receive calls at all, and now can't even login, they send confirmation message but it never comes they make a call for code phone never rings
