Coverage is the first decision check before you buy an Onyx plan. It decides where service can carry your daily use, recurring travel, number needs, and device setup. Start with the places that matter, match them to the right coverage band, then review data, number, voice/SMS, device readiness, and the app quote before checkout.
Key Takeaways
Choose coverage around your real movement, not a shortcut label.
North America currently means United States and Canada in the Onyx catalog.
Data coverage and number service are separate checks inside the plan.
Choose Global when your route crosses supported regions or sits outside a regional band.
Device readiness includes eSIM support, compatible bands, unlocked status where required, and roaming settings.
Before You Start
Know the countries where service needs to work.
Separate daily coverage from occasional travel. A plan for daily life should fit the places you use most before it accounts for a stopover.
Know whether calls, SMS, recovery, or verification matter. Data coverage and number support are connected inside the plan, but they are separate checks.
Confirm that your device supports eSIM before checkout.
Start With The Places That Matter
Write down the places where service must carry your normal life:
where you live
where you work
where you travel often
where you cross borders
where you need calls or SMS
This keeps the decision practical. You are choosing the coverage that protects your normal movement.
Match The Coverage Band
Onyx uses these public coverage bands:
United States
North America
Europe
APAC
MENA
Global
Choose United States when your service need is centered there.
Choose North America when your service need is United States and Canada. North America means United States and Canada in the current Onyx catalog.
Choose Europe, APAC, or MENA when your service need stays inside one of those supported regions.
Choose Global when your movement crosses supported regions or sits outside a regional band.
For Mexico or LATAM routes, use the current coverage view before checkout. North America currently means United States and Canada.
Check Data And Number Support
Data coverage is the base connection. It supports browsing, messaging apps, maps, email, video calls, work, and hotspot use when the selected plan and device support it.
Number service adds calls, SMS, recovery use, verification flows, and a stable contact point.
If communication path matters, check number service before checkout. The plan should carry both the connection and the contact path you expect to use.
Check Voice And SMS
Voice and SMS support follow the number path.
Some users only need data. Others need calls, SMS, verification, or recovery attached to the same account relationship.
If you add an Onyx number, choose the voice/SMS bundle that matches how you communicate. Review the bundle before checkout so the plan reflects the way you expect to be reached.
Check Device Readiness
Your device must support eSIM.
It should also support compatible network bands for the places you plan to use service.
Some phones need to be unlocked before they can activate another mobile line.
After activation, your phone may need roaming enabled or the Onyx line selected for mobile data. Check those settings before you rely on the connection.
Decision Check
Before checkout, confirm the plan supports the way you expect to stay connected.
| Need | Check | Continuity rule | |---|---|---| | Daily service | Primary country and region | Choose the band that covers normal life first. | | Recurring travel | Repeated destinations | Choose the band that covers repeated movement. | | Cross-region movement | Multiple supported regions | Choose Global when the route crosses regional bands. | | Calls and SMS | Number, voice, and SMS support | Add number service when communication path matters. | | Device setup | eSIM, unlocked status, bands, roaming | Confirm the phone can carry the plan before checkout. |
What You’ll See
The coverage path should show:
coverage region
supported countries
available data tiers
number option
voice/SMS bundle
quote review
Use that review as the final pre-payment check. When the app quote shows a different coverage choice than the one you intended, update the plan before checkout.
When To Use Coverage Help
Use coverage help when you need to review a country that matters, compare the coverage view against the plan quote, or confirm number support before checkout.
Keep the useful context ready: the country or route you need, the selected coverage band, whether you need data-only or number service, and the device model.
Keep one-time codes, full card details, private keys, seed phrases, recovery phrases, signing approvals, and wallet backup material private.
