The next 5 years will bring huge changes to the mobile network industry. Network operators will see revenue and usage from voice telephony & SMS decline, while new communications apps will mostly be driven by context & design, not 3GPP standards.
4G networks will continue to be deployed, with 5G coming into view - but data traffic may not grow to the degree expected. WiFi is growing in important - but will only have limited integration with cellular. Net Neutrality concerns will continue to rumble - but most of the new "ideas" like paid priority or sponsored data will fail.
We will also see "multi-stakeholder" issues coming to the fore, where regulators will need to ensure the telecom industry encompasses the needs of users, venues, app developers, IoT companies, brands & Internet players. That said, attempts by Apple and Google to enter the cellular space with SIMs and MVNOs will remain niche
