The Essential Guide to Choosing a Dual SIM Adapter

If you are traveling internationally and wish to purchase a local SIM, then you might wonder where to keep your home SIM. If you have a dual SIM phone, then you can slot it in alongside, and remain contactable on both numbers. Most smartphones however are not dual SIM, including iPhones. The solution is to use a dual SIM adapter.

Dual SIM adapters allow you to use two SIM cards in a phone that was intended for one. This avoids the annoyance of having two phones in your pocket and allows you to keep your current handset. If you want to use an iPhone with two SIMs, then this is your only option.

How Do Dual SIM Adapters Work?

Some models are PASSIVE, meaning that you need to manually switch between SIM cards using the menu that is built in. Some models are ACTIVE, meaning that both SIM cards can be used without manually switching.

Choose the right device and both SIMs will remain active at the same time and both can get phone calls at the same time/one can be put on hold and the other can be answered.

Types of Adapters

A dual SIM adapter is designed to work with an iPhone. However, there are two types of SIMs that you can get. Some are passive, which means that you must manually switch SIM cards using a built-in menu. Other models are active, which means you can use both SIM cards without having to switch cards manually.

Iphone dual SIM adapters come in a range of prices and styles. The internal adapter is inserted into a SIM card slot. It attaches to a SIM on the back of your phone. This adapter plugs directly into your phone. Most internal cards are model-specific, which means you’ll need to find a precise match. The other kind is an external adapter. It is connected to your phone through Bluetooth. An external adapter does not have to be attached to your phone to work.

Are They Easy to Fit?

Dual SIM adaptors are very cheap, but some are better than others, and there are two different kinds on the market, those that are inserted into the SIM card slot, and attach to an extra SIM that is clipped on to the back of the phone, and external adaptors that are connected via Bluetooth.
