Verizon vs T-Mobile: entry plan and upgrade path
Swipe or scroll sideways to compare all options.
| Difference | Verizon My Biz | T-Mobile CoreMobile / ProMobile |
|---|---|---|
| One-line base service | $65/month with eligible billing discounts | $65/month for CoreMobile with AutoPay |
| Advertised base price includes phone? | No | No |
| Base high-speed hotspot | 5GB | 5GB on CoreMobile |
| Base hotspot after allowance | Up to 600Kbps | 3G speeds |
| Larger hotspot option | $5 for 50GB, or $10 Premium Network Experience for 100GB | ProMobile: 200GB hotspot; $85 for one line, $240 for six |
| Upgrade structure | Select paid features on applicable lines | Select a different plan tier |
| Taxes and provider fees | Extra | Extra under the compared offer |
| Main limitation / extra cost | The $65 base does not include the $10 premium-data feature or a phone | CoreMobile’s 5GB hotspot is small; ProMobile costs $20 more for one line |
| Best fit (Sigma assessment) | Verizon tests well and only selected employees need the 100GB hotspot upgrade | T-Mobile tests well and CoreMobile's 5GB or ProMobile's 200GB fits actual use |
| Official sources | Verizon: My Biz Plan: pricing and conditions | T-Mobile: Business wireless plans |

Compare the plan you will actually order
If a Verizon device promotion requires a paid feature, include that feature in the monthly price. Likewise, if a T-Mobile offer requires a higher tier, compare that tier rather than CoreMobile. A saving calculated from a base plan you cannot use with the chosen promotion is not a useful saving.
The practical calculation is straightforward: new recurring service plus equipment payments and required options, minus confirmed credits. Then add any unreimbursed balance on the old account and any period when both services remain active. Keep temporary credits separate from permanent rate differences.
When switching makes sense
A business should have a specific reason to switch: a demonstrated coverage improvement, a lower like-for-like total, or a feature needed by its employees. A phone upgrade alone can be a weak reason if the longer credit period makes future changes expensive.
Test the prospective carrier inside the locations where the existing service causes problems. Use calls, messaging and work applications; a single download test does not reproduce all three. For a Hawaiʻi team serving several islands or varied building types, use representative locations instead of assuming one successful test covers the whole company.
Protect numbers and credits during the move
Keep the old service active while arranging eligible number transfers. Check device unlocking, compatibility and the old account’s outstanding balance before assigning a cutover date. Record any promotional submission deadline and required proof, then check that credits appear as promised.
Choose Verizon when its tested coverage and modular quote solve the requirement. Choose T-Mobile when its tested coverage and relevant tier provide the better complete offer. Staying with the current carrier is a reasonable result if neither alternative produces a measurable improvement.
Six lines: what T-Mobile publishes
T-Mobile publishes six-line totals with AutoPay: CoreMobile at $150 a month ($1,800 a year) and ProMobile at $240 a month ($2,880 a year). Each of lines 9–12 adds $25 on CoreMobile and $40 on ProMobile. Verizon lowers its per-line base price at five or more lines but does not publish the six-line total on its My Biz page, so ask for a written quote at your exact count before comparing.
Questions to ask before you buy
- What is the like-for-like monthly total at our exact line count on each carrier?
- Which switching credits apply, what proof is required and by when?
- Are our devices unlocked and compatible with the new network?
- What remains on current device installment plans?
- Has each carrier passed a call-and-data test at our problem locations?
What Hawaiʻi businesses should check
Run the coverage test on every island and route your team uses before signing. Keep the old service active until each number has transferred, and put any switching credit, its deadline and its proof requirements in writing.
Frequently asked questions
Will a switch offer pay every existing phone balance?
Only the written offer can establish eligible devices, balances, reimbursement limits and timing. Do not assume full reimbursement.
Is T-Mobile cheaper than Verizon for business?
Not at one line: both are $65 a month on their entry plans. T-Mobile’s published multi-line pricing drops faster (six CoreMobile lines are $150), so request both quotes at your actual line count.
