Topped up account, but after 24hrs+, still no service "Emergency calls only"

[insaner]

Hi Mods,

my account expired without my knowledge (no reminders or warnings were sent.. maybe it would be good for PM to send a text message a day or two before expiry if there isn't enough money on the account). So I topped up my account yesterday (before the 90 days were up), but I still have no service, it only says "Emergency calls only". I tried restarting the phone (both a reboot, and a turn off and on), and doing manual network search (it could only see "EXT 2G"), but nothing works. Not sure what to do now. 

Thanks in advance.

Hi all, thank you so much to everyone who tried to help me out solve my issue. I searched around, scratched my head, and finally at some point came across the reason for the problem:

My phone is a Oneplus One, "multi-sim"... but apparently, even though you can shove two sim cards in there, you can actually only use one (kind of). From what I gathered in Oneplus forums, if you want two sims at the same time, one of them has to operate at 2G.. something like that. Which obviously I cannot do with the Public Mobile sim.. or the other provider's sim. So, having removed the other sim, everything is working perfect with the PM sim. *sigh* I didn't realize this had happened, since the time I added the second sim coincided with some time before my PM account used up the remaining funds.. so that also explains why I never received the text message warning me this was about to happen.

Thanks all for your help. Problem solved. (Kind of). Time to go find a multi-sim (android) phone to replace this one.. any recommendations?

@insanerI am glad you figured out the issue, it can be a head scratcher.

Well any cellphones only have a limited # of space for antennas.. especially on a phone that is tailored for China.. some of the Antennas have to be for bands like TD that Canada doesn't use. 1 antenna can only connect 1 network at a time. You would have encountered less of a problem if your phone can do all North American bands, then 1 SIM can use 1 set of frequencies, the other use another. Samsung S9 and 10s do dual SIMs, take both of your SIMs and go to a Samsung store to try it out? That's my preferred way of testing things out.
