So, there are a lot of reasons this might happen.
- You got a new phone! Timehop only has access to sms messages that live on your device, not your entire SMS history (unfortunately).
- you use a third party app for text messages! Unfortunately, this is a tricky thing. We *may* be able to pull your text messages if you use something other than you phone's native text messaging app but, we can't be 100%. We know, this is a pretty big caveat but timetravel is tricky business. We don't make all the rules.
- You're actually using an iPhone. Sadly, your text message history is only available for Android at this time. This is related to the way iOS handles SMS/imessages. If none of the above apply to you and you're still having issues with text messages, let us know!
