To be honest, based on my own experience I have tried to use a browser on my mobile device such as the Opera Browser which has a built-in data saver mode to be able to try and reduce data costs with various faucet sites, however this generally means that there are fewer ads displayed and many of the faucets can detect this and as result they are able to prevent you from claiming under those modes in your mobile device. The only way to avoid it is to use Wi-Fi, if you have access to an unlimited Wi-Fi area.
