It is also possible (and very advisable) to set your handset to 3G-only mode, in which case it can't/won't failover to 2G, for talk it will still fall back on 3G because talk over 4G still hasn't been standardized (4G is aimed mainly at data, the assumption is that talk will use some form of VOIP, possibly SIP). (Then again all talk of 4G is still fairly moot in Israel since afaik we only have a few small testing network so far, no real 4G coverage yet just really fast 3G).
Note that you will finish your battery faster when using 3G only since 2G requires less power, though I assume in newer phones those differences will be smaller due to more efficient chip/transceiver designs.
