IoT comparisons
Technical decisions that come up over and over in IoT projects: network, SIM form factor, APN, IP. Here are the comparisons, no marketing.
LTE-M vs NB-IoT
LTE-M vs NB-IoT: when to pick each
LTE-M wins when the device moves or needs low latency (asset trackers, alarms, wearables). NB-IoT wins when the device is static and needs multi-year battery with deep indoor coverage (meters, parking, sensors). When in doubt, check real coverage at your deployment country before standard specs.
eSIM (eUICC) vs SIM tradicional
eSIM vs traditional SIM in IoT
eSIM (eUICC) wins on flexibility and long-term cost, especially when the product ships across countries. Traditional SIM still wins on simplicity and upfront price when the carrier will not change and volumes are low.
APN privado vs VPN
Private APN vs VPN: what you need
Private APN controls where device traffic exits and which IPs they get. VPN encrypts the path between that exit point and your data center. The norm in serious IoT: both together.
IP fija vs DDNS
Static IP vs DDNS
Static IP is the robust, professional choice when a server must initiate connection to the device. DDNS is a valid workaround for low volume, devices without static IP support, and where DNS latency is acceptable.
LTE Cat-1 vs LTE-M
Cat-1 vs LTE-M
Cat-1 wins if you need more bandwidth (CCTV, POS, gateways) or your target coverage is international without LTE-M guarantee. LTE-M wins if battery or deep indoor coverage is the priority and you can live with its bandwidth limits.
MFF2 (soldada) vs 2FF removible
MFF2 vs 2FF removable
MFF2 removes vandalism, vibration, and dirty contacts; ideal for industrial and outdoor. 2FF removable offers field-swap flexibility and costs less. Today the norm is MFF2 in eUICC form to get the best of both.
SGP.22 (Consumer) vs SGP.32 (IoT)
SGP.22 vs SGP.32
SGP.22 targets devices with a screen and a human user (smartphones, tablets). SGP.32 is built for headless IoT: the device asks the server for a profile, no QR codes, no human input.
Multioperador (Multi-IMSI) vs Roaming clasico
Multi-carrier vs classic roaming
Multi-IMSI swaps the SIM identity to authenticate as a local subscriber in each country; sidesteps permanent-roaming blocks and improves effective coverage. Classic roaming keeps one identity and depends on the home carrier's agreements.
