不开手机data，应该收不到照片。但不明白为什么收不到长短信。能不能收到短信和开不开手机data没关系。你是安卓手机还是苹果手机？
有种情况也许和你手机的APN（手机的Network) 设置有关。这是Chatr公司有关设置的说明：
2. Can I use chatr data with my non-chatr phone?
In order to use chatr data on your own phone, you will need to update your APN settings.
If you have an iPhone/iPad:
For some iOS versions, you can view the APN settings on your device in Settings > Cellular > Cellular Data Network and change it to chatrweb.apn
For iOS5 to iOS8, please click
www.chatrmobile.com/setmyiphone from the internet browser of your iPhone/iPad to get the settings automatically pushed to your device.
For iOS9 or later you can use chatr data on your iPhone/iPad immediately.
If you have another type of phone (Android, Symbian, etc.)
For chatr data:
The data APN <Access Point Name> is chatrweb.apn
The APN Protocol is IPv4v6
The APN Roaming Protocol is IPv4v6
For chatr MMS settings:
The MMS APN <Access Point Name> is chatrweb.apn
The MMS URL is
http://mms.chatrwireless.com
The MMS Proxy address is mmsproxy.chatrwireless.com
The MMS port is 80
注意：在设置时，比如输入：chatrweb.apn，必须是一模一样的，小写字母就打小写字母，不能打大写字母！
