Worldwide coverage with remarkable depth in Asia (Japan, Korea, Singapore, Malaysia, Indonesia, Thailand), on top of Europe and the Americas.

4G/5G networks
Prepaid data on local partner operator networks, in 4G or 5G depending on the destination and the plan you pick.
RedEx app
The RedEx Global eSIM app installs the line, tracks usage and manages several eSIMs. Instant digital delivery after payment, with no physical SIM.
24/7 support
Customer support available 7 days a week and 24 hours a day, by email and through the website, useful if you hit a connection issue mid-trip.
Who is RedEx? A look at the operator
RedEx (RedEx eSIM) is a prepaid travel eSIM provider covering 190+ countries and regions. Like most players in the sector, RedEx runs as an MVNO: no network of its own, but resold access to the local partner operators of each destination, with 4G/5G speeds that depend on the network in use on site.
RedEx's strength is the depth of its catalogue: one of the richest listed on Datadopt, with a wide choice for each destination of fixed volumes (from 500 MB to 50 GB), durations (from 1 to 30 days and beyond) and, the brand's signature, daily plans where the allowance renews every day (1 GB/day, 2 GB/day). This format avoids sizing a global volume in advance: you choose a daily pace and a duration.
Coverage is especially dense in Asia: Japan, South Korea, Singapore, Malaysia, Indonesia, Thailand and China are among the featured destinations, which makes it a serious option for multi-country Asian itineraries. Europe, the Americas and the Middle East are also covered, in country plans as well as regional plans.
On the practical side, delivery is 100% digital: an immediate QR code after payment, installation on eSIM-compatible iPhone and Android, and the RedEx app to track usage and manage several lines. A plan's validity starts on activation on the destination network, not at purchase, so you can buy and install before you leave.
Is RedEx reliable? The service relies on established partner operators, with customer support advertised as 24/7. The usual points to watch in this sector: plans are data only (no calls or texts), fair use applies to the unlimited offers and to the daily plans (reduced speed once the daily allowance is used up), and the refund policy is generally limited to eSIMs that have not been activated. Check your phone's eSIM compatibility before buying.

Trustpilot
3.7/5
1 reviews
Recurring strengths
- Very deep catalogue: a wide choice of volumes and durations for each destination
- Daily plans (1 GB/day, 2 GB/day): a clear format few providers offer
- Dense Asian coverage: Japan, Korea, Singapore, Malaysia, Indonesia, Thailand
- Validity triggered on activation: buy and install before you leave without losing days
Points to watch
- Data-only plans: no calls or texts included
- On daily plans, speed is reduced once the day's allowance is used up: check the daily cap in the plan details
- Speeds vary depending on the local partner operator of each destination
- China: a VPN installed before departure remains essential to reach Google, WhatsApp and Instagram (as with every provider)
Our analysis: RedEx is a relevant choice for travellers in Asia and for those who prefer a daily plan over a global counter, a reassuring format for regular use. For truly unlimited data on a long stay, Holafly remains a benchmark alternative; for a more mature app ecosystem, Airalo and Nomad are safe bets.

Popular destinations covered
⚠️ A warning for China
China blocks Google, WhatsApp, Instagram, Facebook, YouTube and much of the Western web (the Great Firewall). The RedEx eSIM for China relies on a local operator, so the blocking applies. To reach your usual services, install a VPN before you leave (NordVPN, ExpressVPN, ProtonVPN, Mullvad): once you arrive in China, the VPN download sites are themselves blocked.
RedEx plan types
Country plan
An eSIM dedicated to a single destination, with a wide choice of volumes (500 MB to 50 GB) and durations. The most economical format for a focused trip.
Regional plan
A single eSIM for several neighbouring countries (Asia, Europe, the Americas). Handy for a multi-country itinerary, especially Asian tours.
Daily plan
An allowance that renews every day (1 GB/day, 2 GB/day) over the chosen duration. Once the daily allowance is used up, speed is reduced until the next day.
Unlimited plan
Unlimited data subject to fair use on eligible destinations. The high-speed cap is detailed on each plan's page.
RedEx FAQ
How do I activate a RedEx eSIM?▾
After payment, RedEx delivers the eSIM immediately by digital means (QR code). iPhone: Settings → Cellular → Add eSIM → scan the QR. Android: Settings → Network & internet → SIM → Download a SIM. A plan's validity starts on activation on the destination network: you can install the eSIM before you leave without losing days.
Does RedEx offer a discount code?▾
RedEx does not offer a public discount code at the moment. Datadopt's "Subscribe" links include our partner tracking at RedEx's public price, at no extra cost to you. If a code were ever activated, it would be shown on this page.
What is a RedEx daily plan?▾
A plan whose allowance renews every day: for example 1 GB/day for 10 days. Once the daily allowance is used up, speed is reduced until the next day, with no extra charge. It is a reassuring format for regular use (GPS, messaging, social media) without watching a global counter.
Is there a RedEx app?▾
Yes, the RedEx Global eSIM app lets you buy a plan, install the eSIM, track usage and manage several lines from one account. Installation is also possible via QR code without using the app.
Does RedEx work in China?▾
Yes, China is covered, but Google, WhatsApp, Instagram, Facebook and YouTube are blocked by the Great Firewall even via RedEx. Install a VPN (NordVPN, ExpressVPN, Mullvad) on your phone BEFORE you leave: once you are there, the VPN download sites are themselves blocked.
Can I use WhatsApp, TikTok and tethering with RedEx?▾
WhatsApp and TikTok: yes, on every destination (except China without a VPN). Tethering (hotspot): allowed on most RedEx plans; any limits are shown in the plan details on Datadopt.
Does RedEx refund if there is a problem?▾
As with most prepaid eSIM providers, a refund is possible as long as the eSIM has not been activated, then handled case by case in the event of a proven malfunction. Contact RedEx support (available 24/7) with the details of the problem and always test the connection as soon as you arrive.
RedEx or Airalo: which one to choose?▾
RedEx = a very deep catalogue, unique daily plans (1 GB/day) and dense Asian coverage. Airalo = the long-standing market benchmark, a very mature app, strong reputation and a broad unlimited range. Compare on the exact destination of your trip: price gaps vary a lot from one country to another, and both are listed on Datadopt.
Is my phone compatible with RedEx?▾
iPhone XS and later (2018+), Samsung Galaxy S20 and later, Google Pixel 3+, Xiaomi 13+ and most recent eSIM-compatible models. Check for the "EID" field in Settings → General → About (iPhone) or in the SIM settings (Android). See our complete eSIM smartphone compatibility guide for the detailed list of models.
How fast is RedEx data?▾
It depends on the local partner operator: 5G on compatible destinations and plans (Japan, Korea, United States, UAE), 4G/4G+ in most cases. On daily plans, speed is reduced once the day's allowance is used up. The network in use is shown on each plan's page on Datadopt.
