Ok I recently switched to tmobile Nexus 5 and wife is on verizon Galaxy S3. We have been having issues sending and receiving picture mms between us. I believe the issue is the file size she is sending is to large. Does the s3 stock messaging app compress the pic size before sending like a 3rd party app would? Is there a way to change the send size limit on the stock app? I usually use chomp sms but notice issues there too. I am not sure if it could be issues with 4.4 Kit Kat and maybe the app is not optimized yet???? Any help would be appreciated.
