galaxy s4 mini and straight talk apn

[Android Question]

I have an unlocked Samsung galaxy s4 mini and went on the straight talk plan........as of right now I cannot open any mms texts. I am using an ATT sim card and I did as they said and replaced the APN w/ straight talks. any suggestions or help for me?

If you used the APN settings that came with the SIM card (they have 2 different AT&T cards [LTE and non-LTE], and they take different settings), check the APN Type. Make sure there are no spaces after the commas.

Other than that, get on Facebook, go to Straight Talk's page and ask for help. Their best tech support people aren't on the phone, they're on the Facebook page.
