i am having the same issue. I used to receive MMS fine then i started getting "all towers are busy" messages when i make calls and same time, quit being able to receive MMS. Verizon doesn't use Sims so don't give us Sim card fixes. ive called st many times an they had me do the stupid people stuff and factory reset my phone, which did nothing but give me a blank phone that still can't receive MMS. it has had issues since I got it, but not so consistent. haven't received an MMS in over a week. i CAN receive them from myself. just no one else. the expiration date on them is always the time it was received, idk if that makes a difference. this issue is super annoying and st cs sucks. help!
