How Roamzo eSIMs work
From choosing your destination to getting online when you arrive.

- Check your plan’s activation rule
Plan details
Check network coverage, installation and activation before you choose your plan.
Check your phone’s total and per-app mobile data over a representative period. Record its start and end dates, days measured and selected SIM. Divide that period’s total by those days, then multiply by trip days as a starting estimate.
Adjust for changed Wi-Fi access, app messages, photo uploads and app voice or video calls. Where available, offline Google Maps omits live traffic and walking directions.
Compare phone and provider-reported use for the same SIM and check remaining allowance where available; counters can differ. Before buying, check the exact plan’s data allowance, validity, activation rule and eligible top-up options, and check your phone’s compatibility.
Using a laptop through your eSIM hotspot?
First check that your exact plan allows tethering and your devices support it. With a fixed-data plan, the phone and connected laptop share its allowance. Check background transfers on both devices; a phone setting does not control every laptop app.
On an iPhone running iOS 13 or later, Low Data Mode can reduce background use. Choose the travel line for its cellular setting; Wi-Fi has a separate setting. App behaviour and menus can vary. Follow Apple’s Low Data Mode guidance.
For a Pixel Wi-Fi hotspot, Data Saver must be off. Follow Google’s Pixel hotspot instructions; other Android phones and software versions can differ.
On a Windows 11 laptop, set the hotspot’s Wi-Fi connection to metered using Microsoft’s metered-connection guidance. Some background downloads and syncing may be limited, but priority updates can still download. This is not a hard data cap. Ask IT if a managed device prevents changes.
Where the app allows it, defer large cloud sync and nonessential downloads to suitable Wi-Fi. Compare use for the same SIM and time period, and check remaining data in My eSIMs where available; phone and provider readings can differ. Disconnect the laptop or stop sharing when finished.

Plan details
On a compatible dual-SIM phone, keep your usual SIM and choose the travel eSIM for mobile data. WhatsApp can keep your existing registered number. Turn off automatic data switching; your home carrier may still charge for calls, texts or roaming.
If you register that number again in WhatsApp, you may need to verify it by text or call. Ask your home carrier how to keep the number active and reachable.
Installed but no mobile data?
Check the countries covered by your plan, its start rule, remaining validity and data allowance. Turn on the travel line and choose it for mobile data.
On iPhone, open Settings → Cellular → Cellular Data and select that line. On Pixel, open Settings → Network & Internet → SIMs; check Mobile data and Use SIM. Menu names can differ by phone and software. Follow your selected plan’s connection instructions.
For a Roamzo eSIM, enable its data roaming at your destination. If it still will not connect, contact support from your order and do not delete the eSIM. Keep installation details private. Your home carrier may still charge if you keep its line enabled.
