Apparently, you do not understand Suyogdixit's problem. What the user wants is an option to force the iPhone to use "3G/LTE" only. It's also a problem for me in Nigeria. For some reason, the iPhone decides to revert to EDGE which makes using the Internet very frustrating.
On my BlackBerry 10, as well as Android powered devices, I am able to force both devices to use only EDGE, 3G or LTE. What the iPhone does is use an EDGE, 3G or LTE connection whenever it deems it convenient. The user has no control over this and it's been an iOS problem since inception. Considering the number of users who have continuously complained about this, I think Apple should consider including a fix in one of their future updates.
On my BlackBerry smartphone, I can set my connection to these options:
- 4G & 3G & 2G
- 4G & 3G
- 3G & 2G
- 3G
- 2G
When I have the BlackBerry set to the first option, it does exactly what the iPhone does and switches as the device deems convenient. When I set this to the second option (4G & 3G), my BlackBerry insists on staying on 3G & 4G which makes surfing the internet much faster. My iPhone can't do this and I find this very annoying. I have to manually navigate to 'Voice & Data" and select 2G then 3G before it switches back and then stupidly switches back to the slower band (2G). Sometimes I have to share my BlackBerry's internet connection to support the iPhone.
ALL SMARTPHONES HAVE THIS OPTION. APPLE SHOULD FIX THIS!
