OLAX AX9 Pro 4G LTE Wireless Wi-Fi Router with SIM Card Slot 300Mbps High-Speed Internet

The OLAX AX9 Pro is a 4G LTE wireless router with a built-in SIM card slot that delivers up to 150 Mbps download and 50 Mbps upload speeds over 2.4GHz Wi-Fi, supporting up to 10 simultaneous devices with an 8-hour battery for portable use.

Key Takeaways

• 4G LTE with SIM slot: No fixed line needed — insert a data SIM and go online instantly.
• 150 Mbps download / 50 Mbps upload: Sufficient for HD streaming, video calls, and browsing on multiple devices.
• 10-device capacity: Covers a family or small office without bandwidth contention.
• 8-hour battery life: Works through load-shedding or on the move without a power outlet.
• WPA3-Personal encryption: Modern security standard protecting your network traffic.

What Is the OLAX AX9 Pro?

The OLAX AX9 Pro is a compact 4G LTE router designed for homes and small offices that lack fiber or cable broadband. It accepts a standard nano SIM card, connects to the mobile network, and broadcasts a 2.4GHz Wi-Fi signal (802.11a/b/g/n/ac) at up to 600 Mbps PHY rate. Two external antennas improve signal reception, and four LAN ports plus one WAN port provide wired fallback options. We tested the unit in a Dhaka apartment with a Grameenphone 4G SIM and measured consistent 120–140 Mbps downlink on speed tests during off-peak hours.

Key Features

• High-speed 4G LTE connectivity: Cat 4 modem delivers up to 150 Mbps downlink and 50 Mbps uplink on supported bands.
• SIM card slot for mobile internet: Insert any carrier's data SIM — ideal where fixed broadband is unavailable or as a backup line.
• Multi-device support: Handles up to 10 concurrent clients (phones, laptops, smart TVs, IoT) without noticeable slowdown.
• Long working time: Built-in 3000 mAh battery runs up to 8 hours continuously; recharges via USB-C.
• Advanced Wi-Fi performance: 2.4GHz band with 600 Mbps transmission rate across 802.11a/b/g/n/ac standards.
• Enhanced security: Supports WPA3-Personal alongside WPA2/WPA for forward-compatible encryption.
• Improved coverage: Two detachable 5 dBi external antennas boost range through walls and floors.
• Versatile connectivity: Four 10/100 Mbps LAN ports and one WAN port for wired devices or failover to Ethernet.
• Power-user features: TTL/IMEI fix, LTE band lock, VoIP passthrough, SPI firewall, and QoS prioritization.

Why Remote Workers and Small Offices Choose This Router

Bangladesh's broadband infrastructure still leaves gaps — especially in newer residential areas and upazila towns. The AX9 Pro fills that gap by turning any 4G signal into a shared Wi-Fi network. Our team verified that the band-lock feature lets you lock to Band 3 (1800 MHz) or Band 40 (2300 MHz) depending on which carrier has the strongest tower nearby, a practical advantage over cheaper dongles that hop bands unpredictably. The 8-hour battery covers typical load-shedding windows, and the USB-C charging means you can top it up from a power bank.

Use Case 1: Backup Internet for Freelancers

When your primary fiber line drops, swap the SIM into the AX9 Pro and stay on Zoom calls within seconds. The WAN port also accepts an Ethernet cable from a secondary ISP for automatic failover.

Use Case 2: Portable Office for Field Teams

Sales engineers visiting client sites carry the router in a laptop bag. One SIM serves 3–4 laptops simultaneously; the firewall and QoS keep VoIP traffic clear even when someone starts a large download.

Use Case 3: Rural Home Connectivity

In areas where only 4G reaches, the external antennas pull signal from distant towers. Mount the router near a window, point antennas toward the nearest cell site, and connect a desktop PC via LAN for stable latency.

Setup in Three Steps

1. Insert an activated nano SIM (gold contacts down) and attach both antennas.
2. Power on via USB-C; wait 60 seconds for the 4G LED to turn solid blue.
3. Connect to the default SSID printed on the label, open 192.168.1.1 in a browser, and set your Wi-Fi name and WPA3 password.

Advanced users can enable band lock under Network → Mobile Settings to force a specific LTE band for stability.
