Part of the team experience is not having the distractions of home, so regular email contact with home is not encouraged. While some organisations actually say no to doing emails and using devices while on team we are OK about you using them in a small way.  You can probably access your emails via wifi in some of the hotels we use. Sometimes a computer is available in a hotel but nothing is guaranteed. Using your device for data roaming can be quite expensive so you should check with your service provider and then make your decision.
