I switched to Telegram with my fiancée because of troubles with migrating WhatsApp data when she bought a new phone. When we powered up the new phone we realized that WhatsApp message history hadn't been transferred in the device migration (Windows Phone here) and there was some data that we wanted to preserve. WhatsApp on the old phone stopped working because the account had been used on the new phone so we couldn't even look at the chat history without using the SIM card to reactivate it. Reactivating WhatsApp on the old phone involved some extra hassle because the two phones had different SIM card slot sizes. After reactivation we could look at the old messages before moving the SIM card back to the new phone but couldn't transfer them, since WhatsApp chat history transfer on WP requires that both phones have an SD card slot. Being pretty fed up with WhatsApp at that point I found Telegram and have used it ever since.
