How to check strength of signal of mobile phone in iOS with Delphi XE8 in FMX app?

To avoid traffic when the connection is slow, I want to check the strength of the signal.

Then I would show a warning if it's only GRPS or Edge and send only important data packages, and if it's at least 3G oder 4G LTE then I would transfer bigger content with more details.

So, how can I find out the strength of the signal using Delphi XE8 on a Firemonkey App for iOS (and for Android)?
