According to http://www.globalsimcard.co.uk/Data_rates.php GeoSIM have a
roaming agreement with Sweden to Telenor (Vodafone), Telia Mobile
(TeliaSonera), Tele2 and H3G.

on Sweden Vodafone Mobile - Telenor (Vodafone)

Sweden to UK, where it's SMSC is located, but the Swedish operator will not
make any money, only have additional expenses due to increased signaling
That is why many operators have blocked their SMS signaling unless the
operators/service provider have signed a special SMS-agreement.
So for your case, I think you have to ask GeoSIM customer care, if they
(still) support roaming in Sweden (MobileOriginated-SMS and
Also try all the mentioned operators (Telenor, Telia and Tele2).
