Random issues are pretty common with PM. I know when I first started it was annoying that I would often be without service, frequently drop calls, and generally have poor service quality, however, once I factored in the cost savings I figured it was worth the headaches. For example, frequently I get a long delay before a call is even placed after dialling. Sometimes when I call myself from another phone, it can take my phone over 45 seconds to start ringing (tried a few different phones to rule out it being the phone). Often times, even calling a local number in my own area code, it warns me that I am calling long distance and may be billed for it (even though I have Canada wide... and I am just calling my neighbour.) I've actually started to enjoy the random quirks. I know the day when I get that super duper Koodo offer deluxe extreme deal that will be too good to resist, that I will still likely stick around with PM. I am already spoiled by the fact that I never need to worry about getting any huge bills because my phone simply won't let me call anywhere that will cost me extra money. Went travelling in the USA with a friend, I came back owing $0 and never shut off my phone. The friend came back owing over $100 due to it randomly connecting to a US network and the phone auto-updating all their apps and the OS itself.
With that said, often I find when the network is being a bit squirrelly that I try rebooting the phone and if that fails, I eject and reinsert the SIM, that usually makes it happy again.
