I'm the office administrator for a 120-person logistics company. I manage telecom ordering—roughly $60,000 annually across nine vendors—and I report to both operations and finance. So when I compare ZTE 4G LTE vs 5G, I'm not doing it from a spec sheet. I'm doing it from purchase orders, support tickets, and one expensive mistake in 2022.
If you're on the fence about ZTE 4G LTE vs 5G, you're not alone. This question landed on my desk again in Q1 2025, right before our annual device refresh.
Here's what you need to know: this is not a '5G is always better' post. It's a practical comparison based on what I've learned ordering ZTE phones, hotspots, and CPE routers for a team that works in three office locations, a warehouse, and a bunch of customer sites.
I'm going to compare 4G LTE and 5G on five criteria: upfront price, total ownership cost, real-world speed, coverage, and device lifespan. Then I'll give you the scenarios where each one makes sense.
Why Compare ZTE 4G LTE and 5G?
Most buyer guides compare brands. I'm comparing two generations of the same product line because that was the actual decision I had to make. In 2024, after a vendor consolidation project, I standardized our phones and network equipment around ZTE. The question was no longer which brand—it was whether to buy 4G LTE or 5G for the next 24 months.
If you've ever had a finance director ask, 'Why do we need 5G when 4G works?' you know the pressure there. ZTE covers both the device and the network side, which means fewer vendor finger-pointing sessions when something goes wrong. But the budget still has to make sense.
1. Upfront Price: 4G LTE Wins, But Not By As Much As You Think
If you only look at the invoice, 4G LTE is cheaper. At the prices we quoted in February 2025, ZTE's 4G LTE hotspots and entry-level LTE phones came in roughly 30-40% less than their 5G counterparts. A $120 4G hotspot is a real thing. A $200 5G CPE is also a real thing.
The catch is that the price difference narrows when you buy 25 units at once and negotiate a multi-year contract. I got better per-unit pricing on 5G devices than the list price suggested. Don't hold me to the exact number—I'd have to check the last PO—but the gap wasn't the no-brainer I expected.
Verdict: 4G LTE wins on sticker price. 5G is not as far behind as the sticker shock suggests.
2. Total Cost of Ownership: 5G Wins Over Three Years
This is where the phrase 'value over price' gets real. The cheapest device can cost more in the long run.
In 2022, I ordered a batch of 4G LTE hotspots because they were $80 each. The upside was about $2,000 in savings. The risk was that they would be obsolete before we got three years of use out of them. I kept asking myself: is $2,000 worth potentially replacing devices in 18 months? The answer turned out to be no.
Two years later, our bandwidth needs had grown. Cloud backups, video meetings, connected vehicle systems. The 4G LTE hotspots could not keep up. We started seeing support tickets about buffering and dropped calls. The cost of troubleshooting, plus the early refresh, ate the initial savings. I still kick myself for not projecting bandwidth growth before buying.
From experience, a 5G device costs more upfront but typically stays useful longer. On a 3-year TCO basis, 5G won for us.
3. Speed in Real Offices: 5G Is Noticeably Faster
I'm not going to quote theoretical peak speeds. What I can tell you is that our 5G CPE units let three people join Zoom calls while someone uploads a 15-minute video to the client portal. The 4G LTE units did not manage that.
If your team only does email and lightweight ERP, 4G LTE is fine. But for field workers who access CRM files, take videos, and send attachments, the 5G difference is a day-and-night kind of difference. It's the difference between a 40-second wait and a 4-minute wait.
Everything I'd read before 2022 said 4G was enough for office work. My experience with field teams says otherwise.
The most frustrating part of managing device refreshes: we blamed the network for months before realizing the bottleneck was the old 4G hotspot. You'd think a faster plan would solve it, but the device was the ceiling.
Verdict: 5G wins for any team that moves files or uses video.
4. Coverage and Reliability: It Depends on Your Zip Code
Here's the counter-intuitive part: 4G LTE often has better coverage than 5G in rural and warehouse-heavy areas. 5G networks are still being expanded, especially mid-band and mmWave. In a downtown office, 5G is great. In a remote trailer with a metal roof, the 4G signal might be more reliable.
When we installed 5G CPE at a customer's construction trailer, it worked well until the site's metal walls blocked the signal. Our facilities tech checked the outlet with a Fluke 117 multimeter—false alarm, the power was fine—but the signal was the problem. We moved the unit closer to a window and it was fine. That's the kind of nuance you don't get from a spec sheet.
Also worth noting: per FTC guidelines (ftc.gov), claims like '5G' have to be truthful and substantiated. When a vendor says a ZTE router is '5G,' it means the hardware supports 5G network bands—it doesn't promise a stronger signal on a site with zero tower coverage.
Verdict: 5G wins in urban and suburban settings. 4G LTE is still the safer bet for wide-area coverage in places where 5G towers are sparse.
5. Lifespan and Future-Proofing: 5G Has a Longer Useful Life
A 4G LTE phone or router won't stop working overnight. But as carriers re-farm spectrum, operators who bought 4G LTE devices in 2024 may find themselves with fewer available bands by 2028. We saw similar pain during the 3G sunset.
The ZTE Blade A75 5G specs are a good example of future-proofed budget hardware. According to ZTE's official product page (zte.com, accessed February 2025), it has a 6.6-inch HD+ display, 4GB RAM, 128GB storage, and a 5,000mAh battery. For around $150, it gives a field salesperson a better experience than a 4G LTE phone at around $100 over a two-year contract. The 5G radio is the reason.
So if you plan to keep devices past two years, 5G is the better bet.
How to Turn On a Phone (ZTE Edition)
The model doesn't matter much: ZTE phones, including the Blade A75 5G, turn on the same way. Press and hold the power button on the right edge for three to five seconds. Wait for the ZTE logo to appear. That's it.
If the screen stays black, connect it to the charger using the included cable and a wall adapter. Some units in storage drain to zero before they reach your desk. After 15-20 minutes, press and hold the power button again. If the phone vibrates and the screen lights up, you're good.
This sounds basic, but I've had two tickets from people who pressed the screen instead of the side button. If you're staring at a black screen, check the edge of the phone. The power button is on the right side. If the phone still won't power on, try a different outlet or cable. We use a multimeter to rule out bad outlets before blaming the device—plug in the phone, check the outlet voltage, then test the charger. That process has saved us from sending back phones that were never broken.
Which One Should You Buy?
If you're asking me, here's the practical answer:
- Choose 4G LTE if you have a tight budget, your team stays in one city, and your main tools are email and browser apps. A ZTE 4G LTE hotspot as a backup connection is still a no-brainer.
- Choose 5G (like the ZTE Blade A75 5G or a ZTE 5G CPE) if your team works remotely, uploads files, does video calls, or needs a primary internet connection without cable or fiber. The extra upfront money is worth it.
The bottom line: I used to buy on price. After 5 years of managing telecom purchasing—and one expensive batch of 4G hotspots—I now buy on total cost. The cheap option isn't cheap if you're replacing it early or spending hours on support tickets.
As of February 2025, ZTE's official site has current specs for the Blade A75 5G and its 5G CPE lineup. Verify pricing and network band support before you order. Carrier coverage varies, and the device that works great in one state might not work in another.
