Sweden has several well developed mobile networks. Our main telcos, Telia, Tele 2, and Telenor, all provide GSM at 900 and 1800 MHz and UMTS/HSDPA networks. Additionaly, 3 provides UMTS/HSDPA coverage. Pre-paid subscriptions are sold almost everywhere, and at fairly low rates. Consider buying a few pre-paids, should you need to call each other while staying here. Prices are fairly low in the Northern countries, especially compared to using roaming.
The Swedish electric grid delivers an AC current running at 230 V. Our grid uses grounded Schuko sockets for grounded appliances, but also accepts Europlugs. Thus, if you come from a country not using these plugs, be sure to bring a converter, as we at Sjöröd doesn't have the possibility to supply you with such converters.
