Here is a guide to know if an HDC mobile you are planning to buy will be supported by your carrier. It is a general guide for any Chinese Android smartphones out there. This is for those who doesnt know it yet.
So in case you are planning to buy the HDC Galaxy S4 I9500
. You can see that there is a posted information about it that says:
Network Band: GSM 850/900/1800/1900 MHz + WCDMA 850/2100MHz
Well, that is what we need to know first. Take note of that and go to this link: http://maps.mobileworldlive.com/
You can see a page like this:
From that site you can now search for your country, and then select your carrier. Let's have for example; Spain and Vodafone carrier. You can see a result like this:
It says 3G 2100
, that means Vodafone carrier on Spain supports 3G/WCDMA of 2100MHz frequency. Looking back at the network info we have from the HDC Galaxy S4 clone you plan to buy, it says WCDMA 850/2100MHz.
That means your phone is supported and you are able to use the phone in 3G on your carrier (Vodafone Spain)
Simple as that!
