Dual SIM mobile phone

Dual SIM mobile phone

A dual SIM mobile phone is a phone with a slot for two separate SIM cards. Despite being very common in Asia, it hasn’t yet gained traction in Sweden. This could see some change in the future.

But why don’t we use dual SIM mobiles to the same extent in Sweden as other places? The short answer is that carriers are unwilling to sell a mobile that has the ability to have another carrier’s card.

Dual SIM phones still have some issues that need to be resolved; especially when one of the cards is forced to use the older 2G network. But with a little more development and with the future termination of 2G, we can expect that these issues will disappear.

  • Dual SIM mobile phones allow you to have two or more active SIM cards on a phone
  • There are many different models of dual SIM phones
  • The most common solution differs from a primary and secondary card
  • The problem often lies in that the second card has to use the 2G network
  • With dual SIM mobiles you don’t have to buy more mobiles
  • Dual SIM mobiles will help those who have both a work and private mobile
  • Dual SIM mobile telephony has yet to gain traction in Sweden

How does it work?

Different dual SIM mobiles vary in how they work. One version is a mobile with three different slots; two for SIM card and one for memory. This version isn’t as common and has been even less so as of lately. Another version is with two slots; one for SIM card and one where you can choose between another one or a memory card.

A third version has two slots; where both are for SIM cards. This means that you can’t insert a memory card and have to rely on the phone’s own memory. Luckily mobile phone capacity is steadily increasing, while more and more files don’t need to solely be saved on the phone, like music for example.

There are different answers to the questions of how to best organize the phone with two SIM cards. The most common is that you have a primary and secondary card. The primary card will then have access to all the networks, while the secondary only has access to 2G.

Benefits with dual SIM

There are many benefits with being able to use two cards in your mobile at the same time. The most beneficial is probably the the large group of people that have a work and private phone. With a double card you can avoid bringing two phones at all times, and all the extra work that comes with.

Another great use is when you’re abroad. Then you can keep your Swedish SIM card in your mobile while you have a card from the country you’re in. No matter if you call home to Sweden or within the country it can save you a lot of money.

Mobile phones are expensive, and over time it can be a burden for the organization. With dual SIM card a company can save money by avoiding expensive new purchases. Meanwhile they can also avoid bringing two phones everywhere. With so many benefits we can expect that dual SIM card phones will become more common in the future.
