Six Tips on Buying the Perfect Dual Sim Mobiles and Smartphones

Dual SIM mobiles and smartphones that have the capacity to hold two SIM cards are becoming more popular. A popular reason is so that the same handset can be used for both business and personal use, with each retaining separate bills, numbers, and other information as well as a separate ringtone. Frequent travellers to a certain country also benefit from the ability to have two SIM cards in the phone, one for each country. Or if visiting several countries, the original SIM card can be retained while the other card can be changed as required. Otherwise people may use them simply to have access to different pricing plans.

Choosing the Perfect Dual SIM Mobiles and Smartphones

There are various types of dual SIM mobile phone. These have different benefits and drawbacks when it comes to how easy it is to switch between SIM cards. Here are six tips for finding the best dual SIM phones.

Consider a Standby Dual SIM Phone

A distinction can be made between traditional and standby dual SIM phones. Traditional dual SIM phones have two SIM card slots that need to be physically turned on and off. These cannot be used at the same time. By contrast, standby dual SIM phones have two SIM card slots that are usually held on standby. They do not need to be manually switched on and off. When one SIM is in use, the other is temporarily out of service as only one processor is used to control both SIMs.

Popularity of Traditional Dual SIM Phones

Though the standard type of dual SIM phone which requires manual switching between the two SIM cards remains one of the more popular choices, this can largely be put down to cost and inaccessibility rather than any innate advantages.

Advantages of Standby Dual SIM Phones

Indeed, standby dual SIM phones are becoming more popular as people realise their inherent advantages over the older system. Whereas traditional dual SIM phones cannot alert the user to incoming calls on either network, standby dual SIM cards can be on call to receive both. This may be important if the phone is simultaneously used for business and personal use or for two separate business accounts.

Consider an Active Dual SIM Phone

Active dual SIM phones have two SIM card slots that are always available, even when the other one is in use. This is because two processors are used, one to control each SIM.

Advantages of Active Dual SIM Phones

In comparison to standby dual SIM phones, active dual SIM phones have even further advantages. For example, rather than the caller receiving a not reachable message, as typically found with standby dual SIM phones, they will be kept waiting, knowing that the person they are trying to reach is aware of their presence on the other end of the phone. In this way, an active dual SIM phone is rather like a typical landline office phone, with the capability to handle more than one call at a time. This is often better for those using their phone for business use, as it both conveys a more professional image and makes people easier to contact.

Don't Buy a Standby or Active Dual SIM Phone Unnecessarily

On the other hand, not everyone requires a standby or active dual SIM phone that gives dual concurrent use. Those that use a separate SIM just for travelling to a different country, for example, may have no need for anything more than a standard dual SIM phone. In this case, it does not make sense to pay extra for a feature that is not required. Likewise, if the phone is mostly used for making outbound calls, or if there is a clear distinction in hours between SIM card use – for example, one is used between 9 and 5 and the other only after 5 – then a standby or active dual SIM phone may not be necessary.

Check How Many SIM Cards Can be Used

Dual SIM phones do not have to be used with the same two SIM cards. They may be unlocked to be used with more than two different networks.

Using Dual SIM Phones with Different Network Providers

Some dual SIM phones can be used with more than two network providers or calling plans. This means that calling plans and service providers can be mixed and matched to take advantage of the cheapest deals and offers. It enables more flexible and less restrictive phone use. Different phones can remember the settings for various numbers of SIM cards, typically around five. This means there is no need to set up contacts and other features when changing SIM cards. If this is an appealing feature, check the specification to see how many SIM cards the phone can remember and store details for.

Check Out the Battery Life

Dual SIM phones often tend to struggle more than their single SIM equivalents with battery life, because the phone is powering two networks at the same time. However, given the improving battery life of mobiles and smartphones generally, this is rarely a serious problem. Check out specifications before committing to a purchase to make sure that the battery life compares favourably with other models.

Certain Functions Use More Power than Others

Remember that certain functions drain battery power quicker than others. Making calls takes up more battery power than listening to music tracks, for example. While standby times of around 500 to 600 hours are fairly typical, talk time might be around 15 to 20 hours and music playback around 40 to 60 hours. If the battery life is considerably less than these figures, it may be time to shop around a bit further.

Don't Forget to Compare Other Features

Don't forget about other features when looking for a dual SIM phone. Other features that might be important include the camera,,MP3 player,, sat-nav and various apps. Check out the camera resolution, image capture modes, and video functions if taking snapshots and films are essential phone functions. Most modern phones offer apps such as Facebook and Twitter, as well as a number of games, but beyond this they can vary. The weight and profile of the phone may also be important, as phones can tend to differ quite considerably when it comes to size and portability, and the display and user interface are also important features.

Find the Perfect Dual Sim Mobiles and Smartphones on eBay

Dual SIM phones can be easily found in the Mobile Phones & Communication section of eBay, located by following the Electronics & Technology tab from the eBay homepage. From this section, simply select Mobile & Smart Phones to bring up phone listings. Dual SIM phones can be searched for on this page by typing "dual SIM" into the search bar at the top of the screen. Other criteria can then be specified as required, including brand, model, colour, and any other particular features. It is also possible, and sometimes quicker and easier, to use the search function directly from the eBay homepage. It is necessary to add further terms into the search bar when using it from the homepage. For example, try "dual SIM smartphone", "dual SIM mobile" or "dual SIM Nokia".


Dual SIM phones offers uses enhanced flexibility to use their phones, for example, when travelling, using them simultaneously for business and personal use, or even just for taking advantages of the different pricing plans available. There are three basic types of dual SIM phone – standard, standby, and active. Standby and active dual SIM phones offer additional benefits over the traditional type, which requires manually switching between the two SIM cards, but not everyone may benefit from the extra functionality. When it comes to buying dual SIM phones, other factors that should be considered include the number of SIM card details that can be stored, battery life, and general features such as camera, apps, size, and user interface.
