This started as a cheat sheet for myself. I do event tech logistics, which is a polite way of saying 'the person who gets called when a modem dies a few hours before a big launch.' Over the last few years—since about 2022, when 5G CPEs became a regular part of my kits—I've deployed ZTE phones and routers in places where a single failure would have been ugly. So this is not one of those lab-style smartphone reviews. It's the ZTE phones review I actually use when I need answers fast.

Is ZTE a Good Phone Brand?
Short answer: yes, if you match the model to the job. That's kind of a boring answer, but it's the honest one. ZTE is a major telecom equipment manufacturer, not a smartphone startup. In the U.S., most of their phones are budget and midrange—prepaid handsets, basic flip phones, and some Blade series models. They are not trying to compete with $1,000 flagships, and they don't pretend to.
When I first started handling tech for pop-up offices, I assumed cheap phones meant cheap internals. Then I kept seeing a $40 ZTE flip phone outlast phones that cost five times more. Not every ZTE model is a winner, but if you treat them as what they are—functional, no-nonsense devices—they deliver. The ZTE 2780 is a good example: it does calls, texts, contacts, and not much else, and that's exactly what a lot of people need.
Is the ZTE MC7010CA 5G Cellular Modem Worth It?
The MC7010CA is a 5G indoor CPE—a modem/router that pulls 5G from a carrier and turns it into Wi-Fi and Ethernet. I've used it as a main link at trade shows and as a backup when a landline connection went down. Both times, it did what it was supposed to, which in my world is huge.
It's not the flashiest or the cheapest 5G router you can find. But in an emergency, the certainty of having it work is worth more than a few dollars saved. In March 2024, I ordered one for a client's event with only 36 hours before load-in. We paid $40 for priority shipping because the alternative was showing up with no internet. As of January 2025, the MC7010CA is still my go-to when a venue needs reliable connectivity without running ethernet cables through a ceiling.
One thing to verify before buying: the SIM needs a carrier plan provisioned for 5G. According to ZTE's official support pages, the MC7010CA is a dual-mode 5G router for indoor use, but some firmware versions have band restrictions depending on the region. If you're buying from outside your own market, check the band list first. (I've made that mistake. It is not fun.)
What's Actually in the Box?
For the MC7010CA, the box is lean: the modem, a power adapter, one Ethernet cable, and a quick-start guide. Depending on where you buy it, there may also be a SIM tool or a wall-mount bracket. Open the quick-start guide before you install anything, because the box contents list on the official manual is more reliable than any blog post.
The included Ethernet cable is short—around one meter. It's fine for connecting one router to a laptop for setup, but not for reaching from a modem in the basement to an office upstairs. You'll probably want a longer cable if you're planning a permanent install.
If you're buying a used unit, don't trust an open box. A missing power adapter is the most common cause of 'this modem won't power on' after a used purchase.
How Do You Set Up a ZTE 2780?
The ZTE 2780 is a clamshell-style phone—you open it, see the screen and keypad, and close it when you're done. Setup is simple: open the battery cover, insert the SIM card (gold contacts down), put the battery back, and charge it for a few minutes. Then press and hold the power/end key.
The SIM slot is behind the battery, which means you have to turn the phone off and remove the battery if you ever need to swap SIMs. The microSD slot, if your model has one, is usually right next to it.
In my role, I set up these phones for users who don't want a smartphone, so the next step is usually contacts and quick-dial numbers. The menu is basic, but it gets the job done. And the user manual that comes in the box is the fastest way to figure out which buttons do what.
How Do You Turn On a Flip Phone (Including the ZTE 2780)?
Rule of thumb: flip phones don't have a separate power button on the side. The power button is usually the red 'End' key on the keypad. Press and hold it for about three seconds.
People tap it once and say 'it doesn't turn on.' It's not a smartphone screen-wake; you need to hold it until the phone vibrates or shows the carrier logo. If the screen stays dark after five seconds, plug the charger in and wait. A 2780 that's sat in a warehouse can ship with a battery so low it won't even light up the charging icon for a few minutes.
One quirk that showed up on two separate 2780 units: holding the button for too long, like 15 seconds, can trigger a reboot loop on some flip phones. So 'three seconds' isn't just a preference—it's a safe place between tap and too-long.
Why Won't My ZTE MC7010CA Connect?
I'm not a radio engineer, so I can't tell you which 5G band your local tower is using. What I can tell you from pulling a modem out of the box in a parking lot is the order to check:
- SIM. If the SIM isn't activated, nothing else matters. Check the carrier's setup page.
- APN. The modem needs the correct APN from your carrier. This is usually on the carrier support page.
- Location. A 5G CPE doesn't need to be outside, but it does need a window or a spot with a signal. If it's in a metal cabinet, it will likely drop to 4G or nothing.
- Power. Obvious, but a low voltage adapter can cause random reboots. Use the included adapter, not an aftermarket one.
And yes, I've tested all four steps in different combinations. Usually it's the SIM or the APN, not the modem itself.
Is It Worth Paying More for Faster Delivery?
This is where my job gets practical. If you're ordering a spare ZTE phone just to have around, standard shipping is fine. But if the MC7010CA is going to keep a booth running at an event with a firm open time, pay for guaranteed delivery—not just 'expedited.'
I once paid an extra $30 for overnight because a router was needed by morning. The alternative would have been explaining why a $4,000 event had no point-of-sale connection. Extra fees hurt in the moment. Missing a deadline hurts a lot longer.
That's the thing people forget: rush fees pay for certainty, not just speed. A 'probably gets there by then' promise isn't good enough when a client is standing in front of a dead network.
