What to Look for in a Business Phone Plan

Before comparing carriers, know what actually matters for your business:

1. Price Per Line

The most important number. Look at the all-in cost (base + taxes + fees), not just the advertised rate.

2. Data Allocation

Options range from shared data pools to unlimited. For most field workers, 5-10GB is plenty. Unlimited is often overkill.

3. Network Coverage

The best price doesn't matter if your employees can't get signal. Check coverage in your actual service areas.

4. Device Flexibility

Can you bring existing devices? Are you locked into specific phones? What's the upgrade policy?

5. Management Tools

For 10+ lines, you'll want: online portal, bulk device management, usage reporting, spending controls.

Our Recommendation

For most small to mid-size businesses with mobile workforces:

T-Mobile Business Unlimited Plus at $30/line

Why:

• Best value without sacrificing features
• Strong and growing 5G network
• International included (competitors charge $10/day)
• No annual contract required

The $5-10/line you save vs. Verizon adds up fast. At 50 lines, that's $250-500/month — $3,000-6,000/year.

If you're in a very rural area where T-Mobile coverage is weak, Verizon is worth the premium. Otherwise, T-Mobile wins on value.
