is still critical. A valid firmware update ensures that your device connects cleanly to remaining 3G networks, maximizes its maximum 21.6 Mbps HSPA+ potential, fixes Wi-Fi drops, and patches known security issues.
may display a "4G" icon on the dashboard after flashing, but the actual connection remains limited to 3G/HSPA+ speeds.

If you love the form factor of the ZTE MF65M, you can replace it with a modern 4G equivalent without breaking the bank. Look for these highly compatible, budget-friendly 4G portable routers: zte mf65m upgrade to 4g
While you cannot upgrade the network generation from 3G to 4G, there is a different type of upgrade you can perform on a ZTE MF65M: .
If 3G speeds (maxing out around 21 Mbps) are too slow for your needs, it is time to move to an LTE device. ZTE offers several direct 4G successors that provide much higher speeds and better battery life:
After unlocking, you can manually select 4G.

The is not possible through software. It is a 3G-exclusive device. To enjoy modern internet speeds, the best strategy is to purchase a new 4G-enabled device.
Even with 4G signal, wrong APN = slow speeds. To set it:
The ZTE MF65M (specifications here) is a popular, cost-effective 3G HSPA+ mobile hotspot. It was designed for a specific purpose: providing internet access using 3G networks, with HSPA+ download speeds up to 21.6Mbps.
However, you can still optimize your MF65M for the best possible 3G performance or transition to a 4G model. Below is a blog post draft addressing this. Can You Upgrade the to 4G? (The Real Truth) Can’t copy the link right now
Despite the hardware limitations, the term "upgrade" is frequently associated with the MF65M in online marketplaces and forums. This often leads to consumer confusion. In many instances, devices sold as "MF65M" are actually newer models, such as the ZTE MF65M2 or MF65+, which feature updated internal hardware capable of supporting 4G LTE bands.
If you were using the ZTE MF65M as a permanent internet source at home, consider upgrading to a plug-in 4G/5G CPE router (like the Huawei B311 or ZTE MF283). These devices plug into a wall outlet, feature much larger internal antennas for better signal reception, and can handle dozens of connected smart home devices simultaneously.

| Feature | Your Current ZTE MF65M | A Modern 4G Hotspot (e.g., ZTE U10S Pro) | | :--- | :--- | :--- | | | 3G (HSPA+) | 4G LTE, often with LTE-A | | Download Speed | Up to 21.6 Mbps (theoretical) | Up to 229 Mbps (theoretical) | | Connected Devices | Up to 10 | Up to 32 | | Wi-Fi Standard | 802.11 b/g/n (2.4 GHz) | 802.11 b/g/n/ax (Wi-Fi 6) | | Battery Capacity | 1500 mAh | 3000 mAh |
The most straightforward way to upgrade to 4G is to purchase a new 4G router that supports the latest mobile network technology. There are many options available in the market, ranging from budget-friendly to high-end routers. When choosing a new 4G router, consider the following factors:
