What is a Samsung Galaxy J3 (2017) (16GB Gold) SIM-free phone?

A SIM is the small microchip which contains information such as your settings and personal data, including contacts and photos etc. Without a SIM card, your handset is an empty shell waiting to be activated. A SIM effectively powers your handset.
Most mobile phone contracts include both a handset and a SIM, which covers your connectivity, calls, texts and mobile data. However, it is possible to separate the SIM and the handset and go for either a handset deal or SIM-free deal (which are effectively the same thing) or buy the Samsung Galaxy J3 (2017) (16GB Gold) handset up front and outright.

What is a Samsung Galaxy J3 (2017) (16GB Gold) Phone Pre-pay?

A Phone Pre-pay is locked with specific network (SIM CARD included) and you need to topup your plan, you only pay upfront cost for the handset and there is no monthly contract.

What are the benefits of buying a Samsung Galaxy J3 (2017) (16GB Gold) SIM-free phone?

Buying a Samsung Galaxy J3 (2017) (16GB Gold) SIM-free phone is overall much cheaper than the other, often costly, mobile contract options. Plus, you'll have more flexibility with your phone plan, as generally your phone won't be locked to a specific network e.g. O2. This means you're free to shop around different networks to buy a SIM, and you can change your SIM more often. (It is, however, important you check the small print of your handset and check it isn't dependent on a specific SIM card.)
A SIM-free handset means you're going to need a SIM to go with it.

Can Samsung Galaxy J3 (2017) (16GB Gold) SIM free phones be used on any network?

Not necessarily; don't assume that all SIM-free handsets can be used on any network - like an unlocked phone. Some SIM-free handsets will be tied to a specific network e.g 4G, and it's important to check this information. Generally, you should be free to buy a Samsung Galaxy J3 (2017) (16GB Gold) SIM-free handset from any network such as Virgin, O2, O2 and Vodafone, but this is not a given. Don't forget to read the small print when you buy a handset.

Unlocked Samsung Galaxy J3 (2017) (16GB Gold) SIM-free phones?

An Apple device, for example, will lock to the first SIM provider inserted. So always check the small print for exceptions like this.

Can I keep my mobile number?

Yes, it's easy to keep your number. Once you've decided on your new mobile contract, you'll need to ask your existing network for a PAC code (Porting Authorisation Code). It's usually three letters and six numbers long and won't cost you a thing. You now have 30 days to pass this code to your new network supplier, who will then port the number from your old SIM to your new SIM, which means you can keep using your existing mobile number.

No upfront cost Samsung Galaxy J3 (2017) (16GB Gold) deals?
