FAQ
Frequently Asked Questions
What is an eSIM?
An eSIM is a digital SIM built into your phone. It gives you mobile data — internet access. You scan a QR code and you're online. No physical card, no tray tool, no SIM shop. Most phones made after 2018 support it.
But can I make phone calls with it?
An eSIM gives you data, not a phone number. But honestly, who makes regular phone calls anymore? It's 2026 — WhatsApp, FaceTime, Zoom, Telegram all work over data and sound way better than traditional calls. Internet calls are faster and clearer than old-school voice networks. Data is the only thing you need.
Is my device compatible?
If you have an iPhone XR or newer, or a recent Samsung, Google Pixel, or other modern Android, you're good to go. Your device must be carrier-unlocked. We actually ask you to check your settings before you buy — we want you to be confident it'll work.
How do I install my eSIM?
On iPhone: Go to Settings > Cellular > Add eSIM > Use QR Code, then scan the QR code provided in your order confirmation. On Android: Go to Settings > Network & Internet > SIMs > Add eSIM, then scan the QR code. iOS 17.4+ devices can use one-tap install directly from Safari. We recommend installing before you travel so you're ready the moment you land.
Why not just buy a local SIM at the airport?
Picture this: you land in a foreign country, jet-lagged, bags in hand, no internet to even look up directions — and now you have to find a SIM shop, wait in line, hope they speak your language, figure out which plan to buy, swap your SIM with a tiny tool, and pray it works. With dizomo, you set up your eSIM before you even board the plane. Land connected. Be travel ready.
Why not just use my carrier's roaming?
Carrier roaming averages $8-15 per GB. With dizomo, you'll pay as little as $3 for 1GB. That's up to 90% savings — and it's faster to set up. No surprise bills when you get home.
How is dizomo different from other eSIM companies?
Most eSIM companies — including the big ones — are resellers of the same wholesale data. They layer on bloated apps and large support teams, and you pay for that overhead. dizomo is a lean, technically sharp company that uses AI and automation to cut costs. Same coverage, 10-20% lower prices, cleaner experience.
Can I use my eSIM in multiple countries?
It depends on the plan you purchase. Some plans are country-specific, while others cover entire regions such as Europe, Southeast Asia, or North America. Check the coverage details on each plan before purchasing.
What happens when my data runs out?
You can top up anytime right from your dashboard. No need to buy a whole new eSIM. One purchase, one dashboard — track your usage and add data whenever you need. There are no overage charges.
Will it be fast enough?
Yes — you get the same LTE/5G speeds as local carriers. We source our plans from tier-1 network providers. Video calls, streaming, navigation — it all works smoothly.
What if it doesn't work? Can I get a refund?
We make sure you're confident before you pay — we check your device compatibility upfront. If something still goes wrong, email us at support@dizomo.com and we'll refund your money. We offer refunds for eSIM profiles that have not been activated. Simple, no hassle.
Can I keep my regular phone number?
Absolutely. Your eSIM runs alongside your existing SIM. You keep your number for WhatsApp and iMessage, and use the eSIM for data. Best of both worlds.
Do I need Wi-Fi to install the eSIM?
Yes, you need an active internet connection (Wi-Fi or existing mobile data) to download and install the eSIM profile. We recommend installing your eSIM before you travel so you're ready to connect the moment you arrive.
