Good day to everyone. I would really appreciate it if someone can help me with my problem. My sister has a prepaid SIM card on an iphone 5. She activated her roaming service 24 hours before her departure for Singapore. She received this confirmation message: "We're now processing your roaming activation request and you'll receive a text confirmation when you arrive at your country of destination". She's already in Singapore and she has no service and did not receive a text confirmation. She tried searching for networks manually and tried every network available. Her phone was turned off and turned on every time she selected a network to refresh the phone's signal reception. She took the SIM card out and placed in back in. She has around 200 pesos on her balance before leaving for Singapore. But still no service. Please help us, thank you in advance and have a nice day everyone.
