Second Life really is not meant to be run on a phone. Yes there are third party phone apps that will let you use it on a phone, but these are not created or supported by the makers of the product (Linden Lab). Second Life is best run on a desktop system that is directly connected to the internet with a wired connection, and has a descent graphics card. You will also notice in the system requirements neither Android or iOS operating systems are mentioned.

Also the use of a cellphone or tablet is generally Wifi or 3G/4G. Second Life in of itself does not really play well with Wifi. To quote Linden Lab themselves from their own help pages:
"Second Life is not compatible with dial-up internet, satellite internet, or some wireless internet services. Occasionally these types of connection may work with Second LIfe, but Linden Lab is unable to support them or to address issues related to their use. For the best Second Life experience, always use a hard-wired DSL or cable connection. " - http://community.secondlife.com/t5/English-Knowledge-Base/Wifi-and-satellite-connections/ta-p/1296823
I have never attempted to use SL on a phone so would not know how phone viewers work. But if you log in with a normal computer system and need help and I'm around, feel free to hit me up for some help.
