Technological Evolution 3G to 4G/5G
ONI’s mobile internet services operate over MEO’s mobile network, the operator that will proceed with the gradual cease of 3G technology between September 4, 2023 and January 31, 2024, with the aim of strengthening the conditions of coverage, availability and quality associated with the latest generation mobile technologies throughout the national territory, through 4G and 5G networks.
We do not foresee a significant impact to our customers, as, according to our studies, 99% of our customers are already using 4G networks.
We have a transition plan for identified customers who will be users of “3G-only” equipment.
What will happen to the 3G network?
We reinforce our commitment to availability, quality and proximity with access to the most advanced technologies throughout the national territory, through 4G and 5G networks, with greater coverage, speed and capacity.
Therefore, in order to bring you the best service and the most innovative solutions, we will progressively discontinue 3G technology in voice and data services
Benefits of network evolution
Main benefits of 4G and 5G network:
- Better audio quality (HD – High Definition, EVS – Enhanced Voice Service)
- Higher speeds
- Lower latency
- Greater autonomy, due to the lower battery consumption of your mobile equipment
- Be able to fully use all the native features of the most advanced mobile phones
What happens to my phone and SIM card?
Cell phone or Mobile Router
Mobile equipment with 2G and 3G networks will continue to have access to the mobile network using 2G technology.
To a better experience when using voice and data services with 4G and 5G technologies, you must have a compatible mobile device.
Our cards support this technological evolution of mobile networks
What happens to business solutions and applications that use the 3G network?
Considering this discontinuation and in case you have an IoT/M2M solution or another business solution, you should check if one of the 2G, 4G or 5G technologies is suitable for its operation. If so, you will only have to ensure the compatibility of the equipment and/or SIM cards with the necessary technologies. Otherwise, or if you need to use data transmission rates or unsupported features, please contact us.
APNs limited to 3G network
If your company uses an APN limited to the 3G network, we will update it to 4G/5G. If you need to use 4G/5G technologies, you must ensure that this change is accompanied by an equipment update, if these are limited to the 3G network
If you have any questions, contact your account manager or the ONI customer service line, through the number 16500
When will I stop having access to the 3G network?
The 3G network will be progressively disconnected throughout the national territory according to the map:
