It would be more difficult for a researcher to establish rapport with an informant they have not met.
Informants are very important in research because they help the researcher to find out things that would have been otherwise difficult to find. 
Researchers generally prefer to meet their informants in person because:
- they can better read non-verbal cues such as hand gestures 
- there is a chance for a better connection with the informant 
- easier to establish credibility 
All of these ensure that the researcher is able to establish rapport easier with the informant so meeting in person is better.
