IPhone 5 texts sometimes are really slow?

So I just got my iPhone 5 and half the time when I text it can take up to 3 mins to send the text. But sometimes it's just fine and sends it instantly. It doesn't seem matter where I'm or if I'm connected to Wi-Fi or not. Any idea what is wrong? Btw I have Verizon if that matters.

Samsung is better than apple

Maybe some messages are longer than others, or at points, many people may be using the network slowing it down

This typically occurs when coverage is bad in your area or if the network is congested at the time when you sent your text (probably the latter since this issue is sporadic), so you shouldn't have anything to worry about.
