My daughter is using her Nexus 5 in an out of the way place in Todos Santos, Baja Calif. Mexico. She has been there for 2 weeks already, and has another 2 weeks to go. She purchased the $40 Mexico/Caribbean plan through Koodo before she left. She has already reached her limit in outgoing texts, and has not been able to access any data or air time. Is there any flexibility in the plan that would allow her to send more texts since she isn't able to access the data or air time? I would appreciate receiving any suggestions that would help to keep her bill as minimal as possible. Thank you.
