Why should I choose XM16 CAT12 over XH22 CAT4 modems?

The XH22 (CAT4) is limited to 150 Mbps download speed and single-band connections without Carrier Aggregation. The XM16 (CAT12) supports Carrier Aggregation (combining up to 3-4 carrier bands simultaneously), delivering speeds up to 600 Mbps, significantly lower latency, and higher connection stability on crowded cell towers.

What power supply is required for XH22, XM16, and XM55 modems?

XH22 (CAT4) and XM16 (CAT12) modems require 1.2A to 1.5A per port during peak data transfers and IP rotation reconnection. XM55 (5G) modems require up to 1.5A to 2A per port. Industrial 12V 10A or 12V 20A powered Sipolar USB hubs are required to prevent power drops.

Do XM55 and XCPE-25 both support Carrier Aggregation?

Yes! Both the XM55 5G USB dongle and XCPE-25 5G Ethernet CPE share the Qualcomm Snapdragon X55 chipset, natively supporting 5G NR NSA & SA modes along with 7C LTE Carrier Aggregation for maximum speed and band combining.

What is the advantage of XCPE-25 Ethernet 5G modem over USB modems?

The XCPE-25 connects directly via a Gigabit RJ45 Ethernet cable to your network switch or XProxy server, bypassing USB hubs entirely. This eliminates USB driver overhead, bandwidth bottlenecks, and power issues associated with large multi-port USB hubs.

Do all XProxy modems support Web API rotation and IMEI changing?

Yes! XH22, XM16, XM55, and XCPE-25 modems all natively support Web API automated IP rotation and 100% IMEI changing via XProxy software, allowing you to bypass mobile operator tethering restrictions and use affordable phone SIM plans.

Real-World Benchmarks

Theoretical Peak vs. Real-World Farm Speeds

3GPP laboratory specifications represent peak theoretical limits. In actual 24/7 proxy farm operation, speeds depend on cell tower distance, network congestion, and modem thermal dissipation.

Modem Model	Theoretical Peak (3GPP Spec)	Real-World Average	Concurrent Threads	Recommended Proxy Use Case
XH22 (4G CAT4)	150 Mbps DL / 50 Mbps UL	20 – 50 Mbps	2 – 5	Most popular choice for bulk farms. Best value ($38) for single-thread web browsing, anti-detect profiles, social media management, and 90%+ of automation tasks.
XM16 (4G+ CAT12)	600 Mbps DL / 100 Mbps UL	80 – 250 Mbps	2 – 20	Commercial 4G proxy selling, multi-thread web crawlers, HD video streaming, high-speed data harvesting.

SIM Card Form Factors & Slot Sizes

True physical SIM size comparison. Loose Nano SIMs must use a SIM adapter frame to fit Standard and Micro slots.

Key Hardware Technical Factors

Essential physical and operational specifications when choosing XProxy modems.

🔌 Physical Connection Interface

XH22, XM16, and XM55 connect via industrial Sipolar powered USB hubs (USB 2.0 for XH22, USB 3.0 for XM16/XM55). In contrast, XCPE-25 plugs directly into your network switch via a Gigabit RJ45 Ethernet cable, completely eliminating USB hub controller bottlenecks and driver overhead.

⚡ Power Requirements per Port

During peak data transmission and IP rotation reconnection, XH22 (CAT4) and XM16 (CAT12) require 1.2A – 1.5A per port, while XM55 (5G) requires up to 1.5A – 2A per port. Powered Sipolar USB hubs with 12V 10A or 12V 20A adapters are essential to prevent power drops.

📡 Hardware Band Locking

While XH22 operates on single-band connections, XM16, XM55, and XCPE-25 support manual Band Locking via the XProxy dashboard. You can lock modems to uncongested LTE bands (B1/B3/B7) or 5G bands (n78 3.5GHz) for 2x–3x speed gains.

🎴 Physical SIM Slot Standard

The XH22 modem features a Micro SIM slot. The XM16, XM55, XCPE-25, and XLE-5 feature industrial Standard SIM slots with durable full-sized trays designed for continuous hot-swapping without damaging contact pins.

Which Modem Is Right For You?

🔹 Choose XH22 (4G CAT4) for Large-Scale Bulk Farms & Everyday Proxy Tasks

The XH22 is XProxy's #1 best-selling modem for building high-density, large-scale mobile proxy farms. At only $38 per unit, it offers unbeatable ROI. Its 20–50 Mbps real-world speeds effortlessly support single-thread web browsing, anti-detect browser profiles, social media farming (Facebook, Instagram, TikTok), and 90%+ of web automation tools without paying extra for unnecessary bandwidth.

🔹 Choose XM16 (4G+ CAT12) for Commercial 4G Proxy Selling

For commercial 4G mobile proxy reselling, the XM16 (CAT12) is the optimal cost-effective entry point. Commercial clients expect high speeds (80–250 Mbps real-world) and low latency. The XM16 uses Standard SIM cards and combines 3–4 cellular bands simultaneously via Carrier Aggregation.

🔹 Choose XM55 (5G Sub-6) for Commercial 5G Proxy Selling

The XM55 uses Qualcomm's Snapdragon X55 5G modem chipset and Standard SIM cards. Operating on 5G Sub-6 bands with 4 external antennas, it achieves real-world speeds of 300–900 Mbps with 5G NR & 7C Carrier Aggregation, drawing 1.5A–2A per port over Sipolar USB 3.0 hubs. Perfect for selling high-speed 5G mobile proxies.

🔹 Choose XCPE-25 (5G Ethernet CPE) for Enterprise-Grade 5G Proxy Reselling

Also powered by Qualcomm's Snapdragon X55 chipset, the XCPE-25 offers full 5G Carrier Aggregation and uses Standard SIM cards while plugging straight into your Gigabit Ethernet network switch. Each modem gets its own dedicated IP and LAN channel without USB power drops, delivering 400–1,200 Mbps for enterprise proxy farms.

Frequently Asked Questions

Answers about XProxy modem compatibility and network setup.

Will XProxy modems work with cellular SIM cards in my country?+

Yes! All XProxy modems (XH22, XM16, XM55, XCPE-25) are unlocked and support global GSM, LTE, and 5G frequency bands across North America, Europe, Asia, Australia, South America, and Africa.

How does IMEI spoofing help avoid carrier throttling?+

Many mobile operators restrict or block SIM cards when used in data modems or routers. XProxy allows you to change the modem's IMEI to match a standard smartphone IMEI (e.g. iPhone or Samsung Galaxy), allowing you to use cheap unlimited smartphone plans at full 4G/5G speeds.

Which USB Hub should I use for XH22, XM16, or XM55 modems?+

We recommend industrial-grade Sipolar powered USB hubs (10-port, 20-port, or 32-port). For XH22 (CAT4) and XM16 (CAT12) modems, supply at least 1.2A–1.5A per port. For high-speed XM55 (5G) modems, supply 1.5A–2A per port over Sipolar USB 3.0 hubs to deliver adequate power and data bandwidth.
