The difference

Roamza vs the old way of staying connected

No SIM trays. No bill shock. No counting megabytes. Here's exactly how Roamza stacks up against carrier roaming and buying a local SIM.

Feature	Roamza	Carrier roaming	Local SIM
Set up before you fly	2-minute install from your couch	Nothing to do — but you're paying from minute one	Find a shop after you land
Data allowance	Unlimited data — stream, navigate, video-call without counting	Capped daily — $10–25/MB overage is common	Fixed GB — top-ups needed when you run out
Price you see = price you pay	One upfront price, no surprises	Bill shock waiting to happen	Varies by shop, often tourist-priced
Physical SIM swap	Never — keeps your primary SIM untouched	No swap, but locks your line to roaming rates	Yes — ejector pin, fiddly tray, risk of losing your SIM
Works across borders	Regional plans cover multiple countries seamlessly	Yes — but each country adds more charges	No — new SIM needed in every country
Keep your own number	Yes — dual-SIM means your number stays live for calls & texts	Yes — but at premium per-minute rates	No — you get a new local number
Connects on arrival	Auto-connects the moment you land	Auto-connects — and starts the meter	Manual setup after purchase
Hidden fees	None	Carrier surcharges, daily pass fees, overages	Activation fees, plan expiry, reload fees

Unlimited plans include a daily high-speed allowance followed by reduced-speed data. See Fair Use Policy for details.

FAQ

Got questions? We've got you.

An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of inserting a physical SIM, you download a digital profile to your device. It works the same way as a regular SIM — it connects your phone to a mobile network — but without the plastic card.

No. Roamza is a digital eSIM. You receive a QR code by email and install it on your phone — no physical card, no postage, no airport shop visit.

Your eSIM is delivered by email within minutes of payment. You'll receive a QR code, activation instructions, and a link to your order page. Check your inbox (and spam folder) shortly after checkout.

Yes — and we recommend it. Install your eSIM at home over Wi-Fi before you fly. It won't activate or start its validity clock until it connects to a supported network at your destination. That way you're ready to switch on the moment you land.

Most Roamza eSIMs activate when they first connect to a supported network in your destination — not when you buy them. Some plans activate at a fixed time instead. The activation policy for your plan is shown on the plan page and in your order confirmation.

No. Installing the eSIM profile on your phone doesn't activate it. Most plans only activate when the eSIM connects to a local network at your destination. You can safely install at home before you travel.
