Pros and cons

Pros

  • Entry pricing starts at ISK 2,000, so a basic line is cheap to hold.
  • The Otakmarkad unlimited plan is listed at ISK 3,300, a clear single figure for heavy users.
  • Sim only is offered, so you can bring your own handset and avoid a device bundle.
  • 5G is available and Esim is supported, letting you activate without a physical card.
  • Support runs on chat, phone and help centre, including phone and a help centre.

Cons

  • Roaming in the EU is on fair use terms, so frequent travel can carry limits.
  • Plans run on 1 month, which suits short commitments rather than a long fixed deal.
  • Only IS is listed as a market, so the network does not extend to other countries.

Who it suits

  • Icelandic households bundling fixed and mobile with one network
  • People who want a sim only line and will bring their own handset
  • Travellers in the region who will mostly use data at home and rely on fair use abroad

Who should look elsewhere

  • yesss, whose rolling billing suits readers who want to change plans without a set term
  • Lonestar Cell MTN, whose entry price of $0.20 suits readers shopping on headline cost
  • Anyone needing a network in a country other than IS

How it compares on our data

On price alone Sýn sits in the middle of the market rather than at either end. The entry figure of ISK 2,000 places the brand at position 210 of the 258 brands we track, so a cheap basic line is there but it is not an outlier. The Otakmarkad unlimited plan at ISK 3,300 ranks better, at position 91 of the 173 brands compared on unlimited pricing. The gap between those two positions is the practical point: if you want heavy use, the unlimited plan is where Sýn is most competitive, and if you want a small line, the starting price is merely ordinary.

Core features

Three capabilities decide how usable a Sýn line feels day to day. Sim only is available, which means you can take a plan without a new phone and keep the handset you already own. 5G is supported, so the plan is not limited to older network generations. Esim is offered too, so activation does not depend on waiting for a physical card, which is handy if you start a new line quickly or travel between plans. Taken together these three cover the everyday needs most readers look for: your own device, a current network and quick setup.

The company behind it

Sýn is operated by Syn hf, a company based in Iceland. It sells as a network rather than a reseller, so the service and the support sit with the same organisation. Support is offered through chat, phone and help centre, meaning you can reach a person by phone as well as through a help centre, which matters more in Iceland where travel to an in-person store is a real cost. The company structure is simple, with one Icelandic network serving a single home market.

Frequently asked questions

How much does the cheapest Sýn plan cost?+

The lowest entry price is ISK 2,000 a month. That puts Sýn at position 210 of the 258 brands we track on price, so it is a mid-range starting figure rather than the cheapest on the list. Startpakki is the plan that carries that entry price.

What does unlimited data cost with Sýn?+

The Otakmarkad unlimited plan is priced at ISK 3,300. On unlimited pricing Sýn ranks at position 91 of the 173 brands compared, which is a stronger showing than its entry price ranking. Worth checking against your own use if you stream often.

Can I get a Sýn plan without a new phone?+

Yes, Sim only is available, so you can take a plan on a handset you already own. Billing runs on contract and prepaid terms, which means both a contract style and a prepaid style sit alongside it, so the commitment level is yours to choose rather than fixed by the provider.

How long is the commitment on a Sýn plan?+

Plans run on 1 month, so the term is short and you are not tied into a long fixed contract. Billing is listed as contract and prepaid, and the RISAfrelsi data bundle is a prepaid option in its own right, which suits people who prefer to top up rather than commit.

Does Sýn work outside Iceland?+

IS is the only market listed, so the network is a home-market option and the company is based in Iceland. For trips abroad, roaming in the EU runs on fair use terms, so you can still use the line overseas but with fair-use limits rather than unlimited data.

Can I activate a Sýn line without waiting for a card?+

Yes, Esim is supported, so activation can be done on the device itself. 5G is also available on the plans. Between the two, a new line can be set up and then run on a current network without a store visit or a physical SIM arriving in the post.

How do I reach Sýn if something goes wrong?+

Support runs on chat, phone and help centre, so you have phone, chat and a help centre to choose from. The company behind the service is Syn hf, which is the same organisation selling the plans, so support and the network sit together rather than being split between providers.

Should I look at yesss or GETESA instead?+

It depends on billing and where you live. yesss bills on contract, rolling and prepaid, which adds a rolling option Sýn does not list, and GETESA sells on prepaid and contract, the same contract and prepaid pairing as Sýn's contract and prepaid. Sýn's own strength is that it is a network selling in IS only.
