Sweden

At a glance
If you need a data SIM only: Use 3. They have large data allowances (up to 60 GB for 499 SEK), prices for prepaid internet are available here. Most other operators have caps at around 10 GB. Three have decent coverage, they offer LTE at 800, 900, and 2600 MHz and 3G on 900 and 2100 MHz. Coverage map here. Three does not offer 2G at all. Roaming in Denmark is free, provided you've selected the Three Denmark network. You can get a prepaid card in any three store and most shops.

If you need to call and text: Use Comviq. Their "Fastpris" (meaning flatrate in Swedish) plan allows you to call/text as much as you want to any swedish phone number. The cost is based on how much data you want included, the cheapest alternative with 200 MB costs 149 SEK for 30 days of service. After those 30 days your prepaid card will still be able to receive calls/texts, but you need to top up in order to dial out. They also offer 1 week of service for 45 SEK, 200 MB data included. Prices available here. Cards are available in most shops (usually where you can but tobacco). Usually Comviq has hired people who give the cards away for free at the Stockholm Central Station. Comviq supports LTE at 800, 900 and 2600 MHz. They have the best LTE coverage in Sweden as of now. Telenor has the same LTE coverage (they share networks) but Telenor is usually more expensive. 3G is available at 2100 MHz only.

If you need great coverage: There's really one option here: Telia or operators who use Telias network, like Halebop. Halebop is usually cheaper but they do not have any physical stores. You can however get Halebop cards at stores like Pressbyrån and 7-eleven. The best option for short (< 1 month) stays in Sweden with Halebop is probably the plan "Rubbet Liten", which costs 169 SEK and includes 100 calls (no limit in length) to any swedish number, 1000 texts (not just within sweden, to the entire world) and 1 GB of data. The plan is valid for 30 days after which you will only be able to receive calls/texts. Usually you only need Telia if you are going to northen Sweden and plan on staying outside of main roads and towns.

Network technology
Sweden has 4 physical network operators with some MVNS or subsidiaries: Buy the SIM cards in shops, as online you need a Swedish personal number. No registration necessary. Prepaid is called "Kontant".
 * Telia 
 * Tele2 (formerly Comviq) 
 * Telenor (formerly Vodafone Sweden) 
 * 3 (= Tre)

2G/3G Coverage
Telia is market leader with the best coverage in 2G and 3G followed by Tele2 and Telenor. 2G is on 900 and 1800 MHz like everywhere in Europe, 3G is on 900 and 2100 MHz. Tre is a 3G/4G network only roaming with limited coverage mostly in the cities.

4G/LTE Coverage and availability
All major 4 Swedish operators now support 4G/LTE. Tele2 and Telenor have a joint LTE network called Net4Mobility. LTE is on all carriers on 2600 MHz in the cities. Net4Mobility and Tre give more speed in the cities than Telia. The 800 (Telia, Tre), 900 (Net4Mobility)  and 1800 MHz (Telia) frequencies are used additionally. LTE is available on prepaid on all 4 networks.

Telia
Telia, owned by the Swedish TeliaSonera group is market leader in Sweden with the best coverage nationwide in 2G, 3G and 4G (on 800, 1800 and 2600 MHz): Telia 2G 3G 4G coverage map. LTE is available for all prepaid products with up to 20 Mbps speed.

If you are going to northen Sweden and intend to stay out of cities then Telia/Halebop is probably the only network that will have coverage. While Telias 2G GSM/EDGE network has good coverage, their 3G and LTE networks do not have as good coverage as Net4Mobility or Tre. This means that speeds will be lower.
