We are all familiar with 3G/4G/5G/LTE/… and the ever increasing list of acronyms used to describe our daily use of cellphones and mobile data .  Underneath the seemingly simple connectivity of your phone lies a complicated web of manufacturers, national and international regulations, contracts and technologies.

There are a wide variety of 3G/LTE routers on the market and it can be difficult to decide which appliance will be the good choice for you.  The choice will depend on the throughput you expect, its possibility to use several subscriptions at the same time (load balancing) or create one very fast connection with all available connectivity options (bonding).

Cellular devices can be widely categorize as follows

Personal devices: cell phones, 3G dongles, Pocket hotspots and other consumer and prosumer devices.  These will work perfectly under nomal circumstances where there is good signal reception and no network saturation or other sources of interference.  Consumer subscriptions for data connectivity tend to be relatively inexpensive but you need to to be aware of their usage conditiosn and fair access policies.  Exceeding your monthly allowance can very rapidly become very expensive.

Single SIM professional devices: These offer the same single SIM solutions as the personal devices but are more powerful and have other hardware configurations in order to achieve higher speeds consistently or to be used over longer distances.  These professional devices can use enterprise grade 3G/4G connectivity with prioritized service and more providers to choose from.  More information on Single SIM professional devices

Multi-SIM SD-WAN: Based on the latest 3G/4G/5G modules these units allow you to achieve the highest possible speeds and resilience in a wide variety of solutions including the use of multiple carriers for extra high volumes reaching Terabytes monthly if required for a single application.
