While dual SIM phones are quite popular in Asian countries, Apple hasn’t, and most probably, won’t release a dual SIM iPhone. If you do love your iPhone, but have to switch between two SIMs, Magic SIM is your next best option.
Magic SIM is a dual SIM adapter for your iPhone 6 or iPhone 6 Plus, that lets you easily switch between two networks. The adapter has two ends, one with a SIM card slot that stays outside, and the other that goes into the iPhone’s SIM slot along with the other SIM. You can then conceal this arrangement by putting a case, and the network switching can be done from the Settings app, as seen in this video:
Note that unlike actual dual SIM phones, only one SIM card would be active with the Magic SIM. So you won’t be able to receive phone calls on both numbers at the same time. Magic SIM is compatible supports 3G, 4G, LTE, GSM, GPRS, EDGE, CDMA, UMTS, WCDMA and HSDPA.
The Magic SIM adapter costs £24.99 ($40), and can be purchased from here.
