  1. Exclude 39 observations who were sent a text message but who reported not seeing the text message in the follow-up survey, N = 380.
  2. *Controls for city survey was conducted (Ibadan/Ogbomosho) and treatment* city survey was conducted (Model 2).
  3. **Controls for city survey was conducted (Ibadan/Ogbomosho), treatment* city survey was conducted, whether assignment to the treatment/control group was made off-protocol, and treatment* whether survey assignment to the treatment/control group was made off-protocol (Model 3).
  4. ***Controls for city survey was conducted (Ibadan/Ogbomosho), treatment* city survey was conducted, whether assignment to the treatment/control group was made off-protocol, and treatment* whether survey assignment to the treatment/control group was made off-protocol, an indicator variable for surveys conducted at PPMVs, an indicator variable for participant who had a bank account, and an indicator variable for participant could not read or write (Model 4).
