Getting Started with Roamsim
What is an eSIM?
An eSIM (Embedded Subscriber Identity Module) is a digital SIM that lets you activate a cellular plan without needing a physical SIM card.
How do I get started with Roamsim?
Purchase a prepaid data pack here. You choose either a Single Country plan or a Multi-Country pack if you’re traveling across borders.
After checkout, you’ll receive installation instructions by email. Just follow the steps to install your eSIM. Once installed, your eSIM will automatically connect to a local network the moment you land.
That’s it — you're connected and ready to go!
Is my phone eSIM compatible?
Roamsim is compatible with all eSIM enabled devices. Most phones and tablets support eSIM. Click here to check if your device is compatible.
How do I install and activate my eSIM?
After you buy a plan, we’ll email you a QR code and manual setup steps. Installation takes just a few minutes. You can activate your eSIM before you travel — just make sure you're connected to Wi-Fi.
When should I install my eSIM?
We recommend installing your eSIM upon purchase. Rest assured that your data allocation or duration will not start until you have arrived at your destination.
Do I need to unlock my phone?
Yes, your device must be network unlocked to use a Roamsim eSIM.
Can I make calls or send SMS with Roamsim?
Roamsim is a data-only service. Traditional phone calls are not supported.
To stay connected affordably, use apps like WhatsApp, iMessage, or FaceTime for calling and messaging over data.
Will installing a Roamsim eSIM lock my phone?
No. Your phone’s lock status is controlled by your carrier and won’t be affected by installing an eSIM.
How many eSIMs can I store on my device?
This depends on your phone. Some newer iPhones support multiple eSIMs, while others may allow just one. Check your device’s specs for details.
When will I receive my eSIM?
Your eSIM and installation instructions are delivered instantly by email right after you complete your purchase. Most customers receive them within seconds — no waiting required. You can also access these details under the My eSIMs page.
Using Your eSIM
Can I use my eSIM for a hotspot?
Yes! All Roamsim plans support tethering/hotspot sharing.
How do I check usage?
To check your Usage or Top Up, please visit the My eSIMs page.
Can I top up my eSIM
Yes! All Roamsim plans can be Topped up at any time within your validity period. To check your Usage or Top Up, please visit the My eSIMs page.
Can I use my physical SIM at the same time?
Yes! You don’t need to remove your regular SIM. Use your Roamsim for data and switch off roaming on your main line to avoid unexpected charges.
Managing Plans & Payments
What happens if I run out of data?
No worries! Just top up your plan via the My eSIMs page. Since all plans are prepaid, your service stops when your data runs out — no surprise charges.
Will I be charged if I go over my data?
Nope! Roamsim plans are 100% prepaid. Once you’ve used all your data, your service stops.
Can I pause my plan after activating it?
No. Once activated, your plan will run continuously until the data expires or is fully used. We recommend activating only when you’re ready to use it.
Can I renew or extend the data on my eSIM?
Yes! Just top up your existing eSIM through our website. It’s fast and you don’t need to reinstall anything.
Which plan should I choose?
Single-Country Packs are perfect if you’re visiting just one country. If you're traveling across borders, our Multi-Country Packs let you stay connected in multiple destinations with just one eSIM.
Can I get a refund?
Roamsim offers a 100% Money Back guarantee. If you cancel your trip or experience tech issues that we can’t fix; we’ll refund you 100%.
When does my data plan begin?
Your Roamsim data plan begins only when you start using data at your destination — not at the time of installation or purchase. This gives you full control over when your plan is activated.
