Hi all, for those who have been having the same problem as me - Can not send MMS gif animated smilies or photos/pictures to your friends or family members etc. I been emailing back and forth with so many different smarty/3g staff but finally they have decided to "Come clean" and admit the truth. Here's the reply I got by email:
I have taken over this complaint from Jodie whilst she is on holiday. From investigating this further I can see you are correct in saying the reason you are unable to send these animated emojis is due to the file size limit on our end. To try resolve this for you, I spoke with our IT team, and they mentioned a previous case that was similar to your error, but unfortunately, they were unable to raise the limit for the file size on SMS.
I would suggest using a messenger app such as Whatsapp or Facebook messenger to send emojis like this as they won’t have a limit on the app.
I am sorry this wasn’t the answer you were looking for but I hope this answers the confusion when you haven’t been able to send a smiley face!
Hope this helps those with the same problem. It's strange as giffgaff for the same price allow.
