Here’s how: Set up and use a dual SIM in Android


A dual SIM cell phone is not a stupid thing. There are many reasons for this: Surf cheaply abroad, stay reachable on the old number, use a cheap data SIM for surfing. We test dual SIM in Android on the Moto G (2014) with Android Marshmallow and on the Huawei Mate 8 and show you how Android behaves with dual SIM.

Dual SIM: useful for vacation and work

In Germany there aren’t that many top smartphones with two slots for SIM cards. This is a shame because the feature is quite practical. On vacation you can use a local SIM to save roaming fees. In your home country, you can separate work and private life more easily with separate SIM cards in one device.

Dual SIM calls better solved at Huawei

You are less flexible with mobile data. You have to set one of the two SIM cards as the data SIM. In many dual SIM smartphones, only one of the two physical SIM card slots is LTE-capable, while the other is only connected to the GSM antenna. In the example of both the Moto G and the Mate 8, you can change the selection of the data SIM during operation.

Tip: Sign an inexpensive data contract. You cannot make calls with it because it is designed for tablets. Therefore, it is often considerably cheaper. At Telekom there is even the first three months free of charge, after which you can end the test without any follow-up costs.

Dual SIM in Android: conclusion

Dual SIM is convenient and can save costs. Because its uses are so versatile; be it vacation, work or simple cost savings; the purchase of a dual SIM smartphone is worth it for almost everyone.
