I have been in Singapore and my Tmobile phone was roaming just fine, I was getting my phone calls. But one day it just stopped connecting and it says "No Service". I can't access my voicemails since it's not connecting to a phone carrier. I've called customer service and they said they checked my account and it looks fine on their end, there are enough funds on my account for me to roam, and they can't explain why roaming just stopped about 2 weeks ago. (I am on a prepaid plan).
Can somebody help me please? Or at least suggest some ways for me to receive my tmobile voice mails?
Thanks so much.
