What Is Dual Sim Used For
What is Dual SIM and is it for me?
The answer to this question is surprisingly more complex than you lot might initially remember. For many in the Uk Dual SIM may exist a term you're not familiar with. This is because in the UK about phones sold in mainstream stores only have a single SIM slot.
If however you're 1 of our Asian customers, you lot'll probably be wondering how someone could survive with simply one SIM card!
Reasons for having Dual SIM
Having a second phone number might seem like a reason in and of itself. But why might you want a second number? Isn't one plenty?
At that place are a number of practical uses for a 2nd phone number so let's accept a look.
Difficulty moving between providers
As you would expect there are different requirements around the world in regards to network compatibility. This is often why dual SIM slot phones announced in some countries more than others.
In some countries in the past it has been difficult to reliably modify between providers. I solution to this was to sign an agreement with a new provider and use the 2nd slot!
In the UK nosotros take for a long time enjoyed the ability to freely move between mobile operators. We tin can also easily take our current number with united states. This has been part of Uk constabulary since 2003, and has meant that it has been fairly like shooting fish in a barrel to motility between mobile providers.
This type of legislation has only recently been introduced in some countries, or in some cases not at all. So when customers in these areas have moved to a new network provider, they have to get a new card and contract. To make sure people can even so contact them using their former number, they demand to go on their existing SIM bill of fare running.
Issues with coverage
Some other trouble and reason for needing Dual SIM are issues of coverage.
Due to the size of some countries there is no one mobile network which has complete coverage. Fifty-fifty in heavily covered countries such as the United kingdom of great britain and northern ireland this is still an issue in rural areas!
Having two SIM cards allows you take advantage of two network providers that may exist available in different parts of the country. Although just larger countries in theory have this problem, I imagine many of our readers will no doubt comment that mobile coverage is not perfect in the U.k..
Keeping piece of work and home separate
Another reason for Dual SIM is wanting to keep your home life and piece of work separate. This is especially of import for anyone who runs a business from one phone.
Having two SIM cards lets you lot keep calls and messages for two numbers separate. And then you tin can give out your numbers to the appropriate people. Depending on the phone y'all tin can set information technology to prompt which number to call out on every time, or accept defaults. For instance all outgoing calls on SIM 1 and all text messages on SIM 2.
There are of class other reasons for needing dual SIM card slots, these are just some examples. Dual SIM phones are a not bad way to make sure you are constantly available and like shooting fish in a barrel to contact.
So are all Dual SIM phones the same?
At that place are in fact two master versions of Dual SIM phones 'Passive' and 'Active'.
Passive Dual SIM
'Passive' (standby) is when a telephone has a single, shared antenna for both SIM cards. As the proper name suggests both SIM cards spend nearly of their time existence in a passive standby way, waiting to be used.
When you start using i of the SIM cards for either vox or information, the other automatically becomes inactive. Only when you lot have finished using the get-go SIM card can y'all start using the second.
This means you are not able to simultaneously download data using one SIM card while making telephone calls with the other. At first this does seems limiting, but in practice is unlikely to cause too many issues. Particularly as if a line isn't available to take a phone call, it is usually diverted to voicemail automatically by the network provider.
This is the more price-effective solution for consumer Dual SIM smartphones, then by far the more common version y'all will see bachelor.
We can now offer this type of Dual SIM phone from a variety of manufacturers including Motorola, Huawei, CAT, WileyFox, RugGear and Microsoft to name a few.
Some of the peak Dual SIM standby devices at Clove include theMoto G4,Cat S40,Honor vii & Award 5X,Wileyfox SwiftandMicrosoft Lumia 650.
Agile Dual SIM
'Active' refers to phones which benefit from having two antennae, one for each SIM slot. This means you lot tin simultaneously use the ii SIMs. For instance downloading content on SIM1, and making a phone call on SIM two. You can even take two conversations, switching the calls and putting 1 on hold.
There are some disadvantages with this type of Dual SIM phone, the most obvious being cost. There is an actress cost in having ii antennae built in to the phone. Y'all also have increased battery consumption, as the power draw for cellular connections is finer doubled.
Finally at that place is the problem of availability. In countries like the U.k. they are most impossible to source. For case HTC released a Desire 600 with Dual Active SIM card slots, but this was never available in the UK.
Mostly if you specifically need an agile Dual SIM phone you might sacrifice high finish specifications, or buy from a brand you are not familiar with.
Other Things to Consider
When buying a Dual SIM phone nosotros would recommend checking if both slots can utilize 3G/4G connections.
Not all phones have the this functionality bachelor on the second SIM slot. Many cheaper Dual SIM phones only let information on ane SIM carte and just calls/texts (2G) on the second.
As well many manufacturers combine the SD bill of fare and second SIM menu slot to create a hybrid slot. This is typically washed to save on space, when manufacturing a smooth, slim phone. This tin can help meliorate looks, simply again limits functionality, as with this setup you need to choose between a second SIM card or expanding storage with an SD card.
Finally some basic setup is necessary to fully take advantage of the dual SIM capabilities. To brand certain information connections and telephone calls use the SIM card you prefer, you will need to manage your telephone settings advisedly.
Determination
There are some disadvantages with using Dual SIM, but for most people who need this blazon of phone the benefits are far more than important.
Yous will be able to manage your calls and get the coverage you need in areas of poor reception. An increasing number of manufacturers at present offer this type of phone.
Here at Clove Technology nosotros offering a wide choice on our website. As nosotros more often than not source U.k. stock, some of the major brands are missing from the list, however in the future this feature will be available on more than phones giving more choice to customers.
