For Muscat and a journey elsewhere in Oman, start with an Oman country plan. A stop in Dubai changes the coverage question: Horizon’s Middle East plan currently includes Oman but excludes the United Arab Emirates. A regional name is not enough to decide whether one purchase covers the whole itinerary.

Compare the same data allowance and validity
The fixed-data table uses total allowances with 30-day validity. Every figure is a public price in EUR. A larger allowance does not reset each day, and the price alone says nothing about reception.
| Provider | 5 GB / 30 days | 10 GB / 30 days | 20 GB / 30 days |
|---|---|---|---|
| Horizon | €6.83 | €13.47 | €26.75 |
| Airalo | €13.00 | €22.00 | €35.00 |
| Nomad | €11.55 | €18.66 | €31.11 |
| Saily | €13.49 | €21.99 | €35.49 |
At 10 GB / 30 days, Horizon costs €13.47; Nomad lists €18.66, a difference of €5.19. Compare all the rows before choosing: these are dated quotes for the listed offers, not a ranking of every provider or every possible discount.
Budget for the days away from hotel Wi-Fi
A Muscat hotel stay and a road trip towards Nizwa or the coast can spend very different amounts of time away from Wi-Fi. Save the route, accommodation addresses and important booking details before setting off. Mobile reception depends on the area and network; buying more data does not remove a coverage gap.
Count the devices that will share the connection. A passenger uploading photos and a laptop downloading files draw from the same hotspot pool as the phone. If you mainly need messages and navigation, check your actual recent usage before paying for unlimited handset data. If work depends on a connection, arrange a suitable backup rather than treating any travel eSIM as guaranteed connectivity.
The Middle East plan does not include the UAE
Horizon’s Middle East plan is €15.50 for 10 GB / 30 days, compared with €13.47 for Oman alone. The €2.03 difference may be useful for a trip also visiting Qatar or Saudi Arabia, which are in its checked country list. The United Arab Emirates is not included.
For an Oman–Dubai itinerary, price the UAE plan separately or choose a product whose actual country list includes both stops. Separate plans have separate allowances and expiry windows. Do not assume buying the regional plan improves reception within Oman; its extra value is the additional listed destinations.
Unlimited phone data and hotspot are different
Holafly publishes a 7-day unlimited plan at US$51.50 in its USD duration table. The same page specifies 1 GB per day for hotspot sharing. That can suit heavy use on the phone, but it is not unlimited laptop data. The allowance, duration and currency differ from the fixed EUR plans above, so no percentage saving is calculated against it.
Hotspot sharing is free on every Horizon plan.
A laptop or another device uses the purchased pool alongside the phone. Include photo backups, software updates and video meetings in your estimate. For an unlimited plan from another provider, read its current fair-use and hotspot terms before buying.
Horizon plans have no throttling.
Actual reception and speed still depend on the supported network, location, phone and congestion. This article does not contain route tests or speed measurements.
Check the phone before paying
Check device compatibility and that the phone is unlocked. Follow the installation guide over a stable internet connection before departure. Keep the eSIM installed while troubleshooting; deleting it is not a routine connection fix.
Validity does not start until your eSIM first connects to a supported mobile network at your destination.
Horizon’s listed plans are data-only. A data connection is different from a local phone number, ordinary calls or SMS. Your home carrier may still charge for calls, texts or data on its own line. Review both lines’ settings rather than assuming the travel plan changes your home contract.

Short answers
Does 30-day validity mean I must stay for 30 days?
No. It is the expiry window after service begins, not a minimum stay. Compare the shorter plan’s actual price before assuming it costs less, and allow for your arrival and departure dates.
Is 10 GB a daily allowance?
No. In this comparison, 10 GB is the total pool for the plan. Sharing it with another device does not create a second allowance. Check your own recent mobile-data use and leave room for travel days.
