We're moving away from our current VoIP provider and switching to a major wireless carrier. The plan is to issue smartphones to more than 100 employees and use a receptionist or call-center setup for incoming calls. Management says the carrier will configure the phones, but we don't know which mobile-device-management platform will be used yet, and I'm concerned about provisioning, security, support, and ongoing administration. What are the most common problems with a deployment like this, and what policies or technical decisions should we make before rollout?

Billing can become its own full-time problem: roaming, international calling, premium services, insurance, early upgrades, usage limits, and replacement costs. Establish the carrier contract and support boundaries before deployment. Apple Business Manager with automated enrollment is generally straightforward for iPhones; Samsung Knox can help with Android. Whatever platform you choose, verify that devices can be locked, located, reset, and reassigned even after an employee leaves. A phased pilot with several users is much safer than giving out 100 phones at once.
Do not overlook the phone-system design. Confirm how receptionist transfers, queues, hunt groups, call parking, voicemail, shared numbers, texts, and number reassignment will work when an employee changes roles or leaves. Heavy callers will probably need headsets. Test Wi-Fi calling at the office and document that IT supports the corporate service, not every employee's home Wi-Fi or local cellular dead spot. Make sure emergency calling procedures and office-location information are accurate too.
