Simbase SIM cards are registered to specific countries and use roaming agreements to provide global coverage. Data roaming must be enabled for the SIM to connect to local networks. This does not incur additional roaming charges with Simbase.

Without the correct APN settings, your device cannot establish a data connection. The mobile network will block all data traffic, though voice and SMS may still work depending on your device and plan.

The Simbase APN uses SIM-based authentication. Your SIM card's IMSI (International Mobile Subscriber Identity) provides the necessary authentication, eliminating the need for separate credentials.

This commonly occurs with iOS devices after system updates, or with some Android devices after network changes. Save your APN configuration as a separate profile if your device supports it, or keep these settings handy to reconfigure when needed.

Creating two profiles with different MCC/MNC values ensures connectivity across different network partners. Your device will automatically select the appropriate profile based on the available network.

No, you must use "simbase" as the APN name for standard SIM cards. Custom APN names are only available with private APN services for enterprise customers.

These represent different SIM batches with different network profiles. While both use the same "simbase" APN, they require different MCC/MNC values on Android devices for optimal network selection.

The standard Simbase APN works in all countries where we have network partnerships (190+ countries). The same settings apply globally with no changes needed when traveling.

Check that data roaming is enabled, verify your SIM is activated in the dashboard, and ensure your data plan has available balance. Some devices also require a restart after APN configuration.

No, your device must be unlocked (not carrier-locked) to use Simbase SIMs. Carrier-locked devices will reject the SIM or prevent APN configuration.

Generally no, the same APN settings work across all network technologies. However, some older LTE-only devices may require the APN to be set specifically in the LTE APN field.

Devices receive a dynamic private IP address via DHCP from the carrier network. This gets translated to a public IP at the internet breakout point (US by default).

The standard APN provides the same security as typical mobile data connections. For enhanced security, consider private APN options with IPSec or other VPN technologies.
