Pro Tip 1/3
Context Matters
The provider's identity changes with context; they're entities offering specific services in a field. When traveling, find a local SIM card provider to avoid high roaming charges.
Pro Tip 2/3
Service Scope
Providers can range from individuals to large companies, all supplying a service to meet needs. Your tour guide is also a provider of historical knowledge about the city.
Pro Tip 3/3
Not Goods
Provider refers to services, not physical goods. A shop selling products is not typically a 'provider'. She became a provider of legal advice, not legal books.
