Experiencing slow speeds while traveling can be frustrating. With Roafly eSIMs, this is rarely an issue with the eSIM itself. It is usually caused by network routing conflicts or local coverage limits.
Here is how to speed up your connection in seconds:
Step 1: Turn OFF your VPN & Check DNS (Crucial)
eSIM data traffic is already routed securely through international servers to connect you globally. This works very much like a VPN. Running a third-party VPN app (or using custom DNS settings) on top of this creates a routing conflict, which drastically slows down your internet or blocks it entirely.
-
Fix: Turn off any active VPN apps and ensure your device's DNS settings are set to Automatic.
Step 2: Select the Network Manually (Lock the Network)
Whether your Roafly plan supports one or multiple local carriers, your phone's "Automatic" setting can sometimes struggle to maintain a stable connection. Manually selecting and locking the network prevents your phone from constantly searching for signals and often solves speed issues immediately.
-
Check supported networks: Open the Roafly app > My eSIMs > tap your active eSIM details to see the supported local operator(s).
-
iOS: Go to Settings > Cellular > Select your Roafly eSIM > Network Selection. Turn OFF "Automatic" and manually tap the supported network from the list.
-
Android: Go to Settings > Connections > Mobile Networks > Network Operators. Turn OFF "Select automatically" and manually choose the supported network.
Step 3: Refresh Your Connection (Airplane Mode)
Sometimes, your phone just needs a fresh ping to the local cell tower. Turn Airplane Mode ON for 30 seconds, then turn it OFF. This simple trick forces the device to reconnect to the strongest available signal.
Step 4: Force 4G/LTE instead of 5G
If your phone is struggling to hold onto a weak 5G signal, it will feel much slower than a solid 4G connection. Go to your Cellular/Mobile Data settings and change your preferred voice/data line to 4G or LTE.
Why am I seeing 3G or E (Edge)?
If your phone displays "3G" or "E", this is directly related to the local operator's coverage area. While this is less common in highly developed cities, traveling to rural areas, natural parks, or even being inside thick concrete buildings can cause the signal to drop to 3G. This is an infrastructure limitation of that specific location, not a defect in your eSIM.
