When I start at a company I bring my own phone and own data plan. The dev team gets my phone number and nobody else. No work email on my phone, only the work calendar so I know how early to start the day. That way you don't have to carry two phones, be tied to a dual-sim phone or have troubles when you leave the company (in case you use the company phone number for private calls too).
