If you are planning to go abroad but not sure whether your phone will work there then read along.
It’s a big trouble to find whether my phone will work in another country or not. If you travel often then it’s not a good idea that you keep on buying new phones which work in that country. A little drilling will help you to find whether your nokia, samsung, motorola or nexus phone will work in another country or you need to buy a new phone.
Understand Mobile Technologies
Basically there are only two bands GSM and CDMA. GSM is the oldest band and CDMA is relatively new technology. In whatever country you go, you will these two mobile technologies.
Although some of them are using HSDPA which is 3G network. Don’t bother about that. Focus on GSM/CDMA at this point of time.
So, How can someone check which country mobile carrier is using which technology? The answer is simple search google by typing this “Wikipedia Mobile Network Operator of COUNTRY_NAME”. For example if you like to know the status of mobile carriers for Italy then type “wikipedia mobile network operator of italy” this will give you this list: Italy. Similarly you can find the status of China, Australia etc here
That’s not all. If you have found out that mobile operators are using GSM or CDMA or any other network there is one more thing you need to look upon.
Check Frequency Band of that Operator (Country Specific)
Some mobile operates on 900/1800 MHz and some on 850/1900. This info is also present on the previous search we made to find the GSM/CDMA status. Just check the frequency band and remember it for a while because we are going to do the last step.
Check Your Mobile Status (Band and Technology)
Most of you must be aware about whether you are using GSM network or CDMA network but checking frequency band is what we need to check. Go to any good mobile site and check which network your mobile support. For this type in google your mobile name and version along with word “specification”. This will lead you to websites like gsmarena which review almost all mobile phones in the world. For Example if you like to know about samsung galaxy s4 then type “Samsung Galaxy S4 Specification“.
If everything is matching like your mobile supports GSM or CDMA and frequency band too then congratulations you won’t need to buy a new phone while going into a new country.
There is one more thing to note that your phone should be unlocked. Means it should allow you to change SIM cards. There are some mobile providers which bundle your phone with their sim card. Such phones doesn’t accept other sim cards.
Hope this could help you and cut your travelling expenses. Happy Journey
