To activate a SIM CARD Prepaid Elisa, do I need to call a phone, or can I do this through text messages on my smartphone? Are the data packets bought in R-Kioski as well? And can these packages also be activated directly by text on the smartphone?

Let’s correct it, yeah Iceland is included same than with the EU. And also what I mean by that list of countries is that there are unlimited data. In EU post-paids have like 10GBs of data (with Telia) but others may vary. Sorry about the earlier one that didn’t have all the relevant info.

France and Italy should work, I think. At least my plan is (it’s post-paid though). Iceland isn’t included for my plan at least. My plan is Telia (aka Sonera) and the post-paids have DEN, NOR, SWE, FIN, and Baltian countries. Prepaids may vary.

May I ask for your expertised advice?
The situation is I will travel in Iceland and stopover in Helsinki, Furthermore, my plan after Iceland is France and Italy.

What is the suitable sim card for data concentrated?

As you has provided the details of DNA which was bought in Finland, will it be able to use in Iceland, France, Italy?

It would very nice and kind of you if you could share your experience regarding to the mentioned situation 🙂

Please see this article for more info on EU ‘Roam Like At Home’ regulations. Generally, though, you’ll be able to use your SIM and call/text/data package from one EU country in any other, but usually won’t get ‘unlimited’ data while roaming. Exactly what you do get depends on the price you paid for the package and other factors, so you always need to check details directly with the operator.

Both Sonera and Elisa have secondary brands, Sonera network is as Tele Finland and Elisa network as Saunalahti. In fact nowadays pretty much all Elisa consumer services have been branded as Saunalahti. I was just at the R-kioski today and noticed they had Saunalahti Prepaid packages.

Overall mobile data in Finland is typically defined by speed, not by data caps. For example when you have a postpaid subscription, you pay different amount depending if the max speed is 21, 50, 100 or 300 Mbit/s (typically set around 3G, DC-HSPA, LTE and LTE-A data rates). With Elisa/Saunalahti all the postpaid subscription include free, unlimited data at 256 kbit/s.

Around 30€/month should give you a decent, uncapped 4G data subscription through the daily limits (for example Saunalahti/Elisa Prepaid is 0.066€/MB but capped at 0.99€/day).
