Tap*Save*for the new APN.

Reboot the device.Test data and MMS.
On our phone you tap settings , connections tab, more networks , mobile networks, Access point names , then tap the + symbol in the upper right corner to add a new APN.
The apn type line is most likely where your errors are but check all the lines of your custom apn for typos.
I was told at"walmart" by a unhelpful salesman that a at&t go phone zte z998 wouldn't send mms on straight talk and it was the apn type line that was the problem not the phone. The problem was just poor documentation. Cricket wireless web page was no better so I cleaned it up for you. Several of the lines were run together on their webpage so you probably have errors in your apn
As far as cricket pushing the correct apn to your phone don't hold your breath. If that was going to work it would have already done so.
Go over your apn again find the typo's correct them and it should all work.
Good luck
