A second SIM card and national roaming help maintain connection during network outages
Using SIM cards from different mobile operators and connecting to two internet service providers helps maintain connection during network disruptions, though it offers no absolute guarantee. National roaming is sufficient for voice calls, while xPON technology protects home internet. This was reported by RBC-Ukraine (Дмитро Левицький) citing Stanislav Prybytko, according to the portal PromPolitInform.
Deputy Minister of Digital Transformation Stanislav Prybytko emphasised that using SIM cards from different operators is a practical step to ensure reliable mobile internet. Having an extra card provides an alternative connection channel if one carrier encounters issues.
At the same time, buying multiple cards is unnecessary for standard voice calls. The official noted that National Roaming features are sufficient to maintain voice connection during outages.
Impact of Shared Infrastructure on Internet Providers
Having agreements with two different fixed-line internet providers can also serve as a backup, but it does not fully guarantee protection against broad blackouts. The effectiveness of this approach depends on network topology.
“Regarding home internet — two providers can be useful, but it is not a guarantee. If they use the same backbone or shared infrastructure, damage to it can affect both simultaneously,” Prybytko noted.
Energy-Independent Home Internet via xPON
The most reliable method to maintain home internet during power cuts is using energy-independent xPON optical technology. The primary advantage of this system is the absence of active intermediate equipment needing power between the provider and the customer.
“Therefore, during a blackout, you only need to power your Wi-Fi router and modem using a power bank or another backup power source to stay online,” the Deputy Minister of Digital Transformation added.
