No SIM, No Problem: How the Firstnum M4 eSIM Hotspot Holds Up
In a world where being online is almost as essential as carrying your passport, a reliable mobile hotspot can make all the difference, especially when traveling or working remotely. The Firstnum M4 LTE eSIM Mobile Hotspot is designed for people who don’t want to rely on patchy public Wi-Fi or worry about roaming charges. Compact, contract-free, and surprisingly easy to use, this device might just be the simple solution for staying connected across the U.S. and Mexico.
Let’s take a closer look at what this travel-sized gadget offers—and where it might fall short.
What’s the Big Deal?
- Pocket-sized & lightweight: Compact enough to slip into your pocket or pouch—you’ll practically forget it’s there, but it won’t forget to keep you online
- eSIM smartness: With built-in eSIM, there’s no need to hunt for SIM cards. Just power it up, activate, and you’re off—pure freedom
- Works across the U.S. & Mexico: Automatically switches between major networks (AT&T, T‑Mobile, Verizon, Telmex, América Móvil)—no sticky settings or confusing tech needed
- Supports up to 10 devices: Bring along your smartphone, laptop, tablet, and the whole gang—this hotspot’s got you covered
- 1GB free data—every single month: That’s included for life. Perfect for light browsing, emails, or trying it out before buying more
Speed, Battery & Everyday Use
This is a 4G LTE device, so streaming a quick video or Zoom’ing on the go feels smooth and reliable—no slow-loading mishaps. And let’s talk battery: it packs a 3,000 mAh cell that reportedly powers about 6–8 hours of continuous use—ideal for a full morning of remote work or a day wandering the museum.
Setup: Piece of Cake
- Power it on.
- Connect your device to its Wi‑Fi network.
- Head to
192.168.1.1in your browser. - Use admin credentials (admin / FIRSTNUM) to set it up.
Tip: switch to “4G ONLY” for a more reliable, faster connection.
Easy peasy.
Customer Love (and “meh” moments)
Many users are head-over-heels, like:
“It got the esim technology making it hassle‑free… 1 GB of free US data per month which is a fantastic bonus…”
“Supports up to 10 devices… Battery life was impressive, lasting me nearly a full workday…”
Others have raised an eyebrow:
- One user notes there’s no way to customize the Wi‑Fi password—security buffs, take note!
- A few flagged the data top-up system as a tad confusing, and battery life varied from user to user .
Who’s It For?
| Ideal For… | Why It Works |
|---|---|
| Light Travelers & Casual Users | Monthly free 1 GB beats surprise roaming bills |
| Small Groups or Families | Connect up to 10 devices without slowdown |
| Remote Workers & Digital Nomads | Sturdy LTE internet wherever your day takes you |
| Tourists in U.S./Mexico | No extra SIM, no hold-ups at arrival |
But if you’re a heavy streamer, gamer, or need global coverage—this might not be your primary hotspot. It’s not 5G, and its data focus is U.S./Mexico only.
Pricing & Value
Online, it hovers around $99–$159 USD, depending on where you shop. For that, you get a solid, no-contract hotspot that could save you a ton over expensive roaming fees. Compare that to international roaming daypacks or single-country SIMs—this one gives overall flexibility, especially if you’re mixing work and play.

- Works with up to 10 devices
- 1 GB free data monthly lifetime
