Prepaid SIM Guide

How to use a prepaid SIM?

To use a prepaid SIM, make sure you have got an Unlocked GSM phone, our SIM cannot be used in any CDMA phone.

Normally, most GSM phones are sold unlocked but carrier may locked the phone to their network if you buy it with a cellular plan from them. Contact your network carrier to check whether your phone is locked or to unlock your phone.

What is data package?

Data package of a prepaid SIM specifies three parameters:

  1. The amount of data usage
  2. The valid period of the data usage
  3. The location that support the data usage

Because most of our SIMs are sold with a default data package, you will also see these parameters in the name of a product.

The included package of the SIM will be effective once the SIM is activated and will expire after the valid period, though few may allow you to resubscribe the package.

You should choose a SIM base on these three main parameters mentioned above.

Another type of prepaid SIM is self-selection data package, which you may choose to subscribe a package from a list of presetted packages.

This kind of SIM contains a specified stored value and the cost of the selected data package will be deducted from the stored value.

The presetted packages can be simplily applied by sending a subscription code using the prepaid SIM. The subscription code(s) and its related cost will be displayed on the product pages.

What is the expiry date of prepaid SIM?

Expiry date is the last day that you can activate the SIM. No prepaid SIM can be activated beyond the expiry date.

Please make sure you activate the SIM before the expiry date.

How to activate the SIM? Where should I activate the SIM?

The SIM will be activated once it is inserted into your phone in the supported countries and the valid period will be started counting.

Most of our SIM can be activated at the supported country(ies) of the SIM but some of it may require specific location to be activated.

This information is being shown on the product page for each product, please make sure you can activate the SIM at the require destination before purchasing.

How long would the service last?

There is a valid period for the data package and a valid period for the SIM itself. Both of the valid period will start counting at the moment that the SIM is activated.

Within the valid period of the SIM, you may add value to the SIM card to resubscribe data packages.

You may use your phone as a personal hotspot or insert it into a WIFI egg to share internet connection.

For WIFI egg setting, you may need to insert the SIM into a mobile phone to set up the Access Point Name (APN) before plugging it into a WIFI egg.

Though internet connection can be shared through personal hotspot, it is not recommended, too much network usage may exhaust the data usage in a short period of time. Maximum person to share a single data SIM should be limited to 2.
