AIRCARD SUBSCRIPTION:

  • As most users are aware of this they need to pay a bundle sum of money to renew the subscription plan every month from the activation of the data plan on the user’s device.
  • This price is mostly fixed and when the allotted amount of data as per subscription plan is exhausted the user is charged extra for the extra amount of MB/GB(Network Data unit) usage.

  • They enable users to have more hasslefree high speed network on their devices wherever they travel to.
  • It can immediately access to another network without any delay.
  • Based on cellular network availability wherever the mobile tower is present u can connect in those regions.
  • Wireless radios require a wireless network(Hotspot or public network)  in order to connect whereas an aircard does not.

NETWORKS AND VARYING SPEEDS:

  • Obviously using an aircard on a 4g network will provide blazing speeds when compared to using an aircard on a 3g cellular network.
  • However based on differences between cellular networks sometimes 3g cellular networks may provide more speed than 4g networks.
