Siima vs Nomad 2026
Nomad hooks new buyers with a free 1GB trial and pays existing ones $5 to bring a friend — a real acquisition machine, but it runs on an account and a dashboard. Siima skips the account entirely: no trial, no referral credits, just a browser checkout with the fee breakdown shown before you pay. The trade is honesty about cost versus a free taste before you commit.
A dashboard-and-referral eSIM vs a one-off checkout
Nomad covers 200+ destinations with prepaid, data-only plans, and its checkout is built to keep you coming back: a signed-in account tracks every plan you've bought, a personal referral code earns $5 off for both you and whoever redeems it, and a free 1GB/3-day trial (no card needed) lets new users test a network before spending anything. It's a genuinely useful acquisition loop if you travel often enough to make an account worth having.
Siima doesn't build any of that. There's no dashboard to log into, no referral code to share, no free tier — you land on a country page, pick a data size, and pay. The upside is nothing to set up and nothing tracking your purchase history; the downside is there's no way to try a network for free before committing.
| What you're comparing | Siima | Nomad |
|---|---|---|
| Buying the eSIM | Browser, no account | Website or app, account required |
| First-time cost | Pay from GB #1 | Free 1GB / 3 days in 48-76 destinations |
| Seeing the real cost | Plan + service fee + processing fee shown separately | One bundled price per plan tier |
| Bringing a friend | No mechanism | $5 credit each via referral code |
The free trial is real, but it comes with a login
Nomad's 1GB/3-day trial is a genuinely useful way to check a destination's signal before buying a bigger plan, and it doesn't ask for a credit card up front. What it does ask for is an account — the trial is tied to a login, and Nomad's help center is explicit that it only works once per new user, including for anyone who's tried to route around it with a second referral code. If you just want a quick eSIM for one trip and never plan to open the account again, that's a login you're creating for a single free gigabyte.
Siima has no trial to weigh that against — every GB is paid from the start. What you get instead is nothing to sign into afterward: no dashboard holding your purchase history, no password to a travel-eSIM account you'll use twice a year at most.
Bundled price vs itemized price
Nomad prices each plan as a single figure — a fixed amount of data for a fixed number of days in a country or region, no activation fees or roaming surcharges layered on top. That's straightforward, but like most competitors it doesn't break out what portion of that number is the data cost versus Nomad's own margin.
Siima's checkout splits the same purchase into the plan cost, a service fee, and a processing fee, each shown as its own line before you confirm. Neither approach is automatically cheaper — Nomad's low-end per-GB rates (under $1/GB on some US and regional plans) can beat Siima's on a specific route — but only one of them shows you the seams.
Buying through an AI assistant
Siima runs a public MCP server at api.siima.online/mcp, so an AI assistant like Claude or ChatGPT can search plans and hand you a checkout link without you opening an app, a website, or a login screen yourself. Nomad's flow assumes a signed-in human at every step — the account and referral system that make it sticky for repeat buyers have no equivalent path for an agent to complete a purchase on your behalf.
Where Nomad still has the edge
If you travel enough to actually use a dashboard, Nomad's model pays off: a free trial to de-risk a new country, referral credits that add up if your friends travel too, and one login holding every plan you've ever bought across 200+ destinations instead of a fresh checkout each time. For someone who buys eSIMs a few times a year and doesn't mind an account, that loyalty layer is a real advantage — Siima trades it away on purpose to keep checkout to a single pass with nothing to remember afterward.
