Dual SIM phones – Everything you need to know

If you’ve been looking at one of our rugged phones or smartphones, you may have already noticed that they are either Dual-SIM, or Hybrid-Dual SIM Devices, but what does this mean for you? As you can gather from the name Dual-SIM means that the user is able to insert two sim cards or either one sim card and one microSD card at the same time. Not only is this feature more convenient for the user but it’s also cost-effective!

Other Advantages Include 

  • If you travel regularly this feature is ideal for you as you will be able to use your international sim card as well as your normal sim card avoiding international cellular network charges.
  • With two sim cards, you will be able to have different data plans on different networks that may work out cheaper for you.
  • You will now be able to have one phone with two sim cards that can be for both work and your personal life.

Currently, not all Dual-SIM phones function in the same way, therefore it is important to keep in mind that there are two types of dual SIM phones that a user can purchase, which include Dual SIM Active and Dual SIM Standby. Dual-SIM Active means that two SIM cards can be active at once, for example, a user will be able to receive a call on one SIM and take a call on the second SIM, basically, the two SIMS can be active at once, given your device supports 4G LTE technology as this is what makes it possible. Dual-SIM Standby means both SIMS will be active at all times, however, you may only choose one at a time for data and if one sim is active on a call the other will not be able to take calls and this will be forwarded to its voicemail. It will however be available to take a call again once the other line is no longer active.

How to use a memory card with a Dual SIM phone

Many of our Dual SIM phones combine the microSD slots and the SIM slots together to support either a SIM card or a microSD card, which allows the phone to add additional storage space to the device if you would like. In this case, you can use either two SIM cards, or one SIM and one microSD card, but not all three cards at once.

So what’s the best and most affordable Dual-SIM device that we currently offer at Rugged SA?

We recommend the UleFone Armor 8 Pro for only R5699! Released in 2021 it comes with the latest Android software, 6GB RAM, 128GB ROM and most importantly it features Dual-SIM Standby and supports expandable memory storage up to 256GB!  This means that if you purchase the UleFone Armor 8 Pro you will be able to use two SIM cards at once or use one SIM card and add an additional 256GB microSD card to the already existing 128GB ROM on the phone, but remember you will not be able to use all three at once. The final thing that you need to consider when buying either a rugged phone or smartphone from us is that most Dual-SIM devices require either a micro-SIM or a Nano-SIM, so be sure to check out the specifications on your interested device before purchasing it. If you are still unsure about your device don’t hesitate to reach out to us and ask our friendly sales team for help!
