Nomad eSIM review: plans, coverage and the catches

Nomad's best feature is a sentence in its help center. "Your Nomad eSIM validity begins only once activated, not at installation."

Activation, in Nomad's words

The help article (dated August 24, 2026 on the page) tells you to install before the trip, since installing needs a stable connection, and says installing will not activate the eSIM. The Japan page adds the mechanics: the plan starts automatically once the eSIM connects to the destination network. You can also leave it unstarted for up to 60 days after purchase. After that it activates by itself and the expiry begins.

Compare that with Airalo, whose own help page says some packages start counting at install. Our Airalo review covers that rule.

The Japan plan

The plan I'd anchor on is 5 GB for 30 days at $10 (November 2, 2026). Nomad's Japan page names KDDI au, SoftBank. It is data only.

The page lists fixed plans of 1, 3, 5, 10, 20 and 50 GB, plus unlimited plans of 3, 7, 14 and 21 days. The dollar figures here are Nomad's own, from its page data, and the page title reads "from US$ 4". Check the final price at checkout.

Sale prices come and go. On that date the 10 GB and 20 GB Japan plans carried an "on sale" tag, and so did the 20 GB and 50 GB US plans. A sale is not the price. Plan around the list.

Unlimited, with a ceiling

For the US, Nomad sells unlimited packages of 3, 5 and 7 days. The 7-day plan costs $23. Nomad's plan details give its speed rule as "2GB/day at 4G/5G. 1 Mbps after 2GB". So it is unlimited in the way a buffet is: the plate size is capped.

If you'd burn 4 GB a day streaming and hotspotting, a big fixed plan wins. Try that hypothetical in the calculator: 4 GB a day over a week is 28 GB.

Hotspot, numbers and top-ups

Nomad's FAQ on the Japan and USA pages answers "Is hotspot and tethering supported?" with a yes. A local phone number comes with only some plans, so check the plan details. The pages offer no blanket promise.

Adding data works through the Manage page on the app or site: choose the eSIM, then "Add more data". An add-on starts automatically once the original data runs out or expires. If the original plan expired first, the leftover data is lost. Some Nomad eSIMs don't support add-ons at all, and the help article says you can't buy one while in the UAE or India. That last rule is local law, per Nomad. Still, it matters if your route includes either.

Who it suits

Pick Nomad if activation timing worries you or you want a menu from 1 GB to 50 GB. For the US head-to-head, read Airalo against Nomad and the US eSIM comparison. All plans live under eSIM plans, and the travel eSIM roundup places Nomad among the rest.

The page cites 47,733 reviews on Trustpilot. Those are Nomad's own figures, so I don't lean on them.

I'd score it 8 out of 10. Nobody here has used it, so the score weighs price, the limits Nomad states and how plainly the terms read. The rules read plainly. The thin phone-number detail costs a few points.
