Not being tied to a mobile contract is the primary reason for the booming of unlocked phones in the market. Many of the subscriber's cries would include hidden charges, unaware ringtone subscriptions and more that they actually do not have any control of. Generally, based on the video on Phphotovideo.com, they feel much more confident in using unlocked phones and have the freedom to switch GSM carrier anytime. Despite this freedom, though, unlocked phones do not just work with any carriers. There is a matching game happening that any user should be aware of.

Below is a quick step by step guide in making sure that their phone will work with a chosen career.

First, select a wireless GSM Carrier.

Using an unlocked phone in the United States leaves them to two major options, either AT&T and T-Mobile. Note that there are many Mobile Virtual Network Operators that are low-priced, but they only have limited choices for high-end phones.

Second, determine The Carrier's Frequency.

If for example, they choose AT&T, which is the most commonly used, take note that they use 850 and 1900 MHz for 2G and 3G service and bands 2, 4, and 17 for LTE according to Lifehacker.com . They need a phone that supports all those and it will be working 100% fine. The list of frequencies per carrier can be found below.

Then, choose a Matching Mobile Device

Once frequency details have been noted, ensure that the customer's selected mobile unit will support that frequency. Simply look at the specifications of the unit or model that they are planning to buy.

Finally, Setting Up. Most carriers would have an automatic set up once the customers opened their phones for the first time. In cases, t wouldn't, just always assure that the International Mobile Station Equipment Identity (IMEI) of the unlocked phone is associated with their account. They may ask assistance from the staff of the carriers to associate the account with the phone's specific settings.

The whole process takes about less than an hour. The decision power is in the user's hands. There are existing reviews and referrals from friends for the best options you have in GSM Carriers and mobile units.
