I am using Apple iPhone 5S (India) and as 4G services are now available in my country my phone is still not supporting it. Is it something to do with the bandwidth? Or do I have to change something in settings? I am using Airtel as the service provider. Is this an issue with the service provider or with my phone?
My phone is not supporting 4G, though its specifications say it does
You need to do a simple test to see if you are on 4G. Check near the network bar of your phone, if you see 4G or LTE written there, then you can be sure that you have 4G running on it. However, this can only happen when you are on 4G network, have a 4G SIM and as you mentioned a 4G phone. Enable LTE on your iPhone by going to: Settings -> Cellular/Mobile -> Enable LTE.
Also, verify if the latest version of iOS available for your phone is installed on your phone. To do that connect your phone to your computer and detect it in iTunes. ITunes automatically displays a pop-up stating whether you need an update.
Verification is also to be done with regards to the SIM card you are having. The SIM card should be 4G Ready. If you don't have a 4G SIM card ready. Visit the nearest Airtel Relationship outlet and you can get the new 4G enabled SIM in exchange of the old one.
This should resolve your problem.
