Yes! If the requirement of an application changes after installation the tariff can be easily adjusted. Our multi-network SIMs are available with flexible tariffs to provide you with the best option to control costs. The flexible data bundles vary from 1MB to 500GB and beyond.
If you go over the data allowance specified in your data plan, we will reach out to you to inform you and offer to upgrade your current plan. Exceeding your specified data allowance may induce a fee and/or may result in a temporary deactivation.
Your device must include the country code when calling/texting a number. E.g. When sending an SMS message or making a call to 07123 456 789, enter this as 00447123456789 or +447123456789.
When calling or texting a CSL SIM number, the country code needs to be included. E.g. The number 37123456789 needs to have a 00 or + included before it (i.e. 0037123456789 or +37123456789).
CSL SIMs come in three sizes. Standard, Micro and Nano. By default, the standard SIM size is sent out when making an order. To order a Micro or Nano sized SIM, please include the size you would like in the Special Instructions box during checkout.
All CSL SIMs are managed under a private APN network. To get your device working over the data using a CSL SIM, you must enter in your device the APN details included with your SIM order. If you do not know the APN details or have lost them, please contact our Technical Support team on +44 1895 474 444 or support@csl-group.com for assistance. Please have your SIM ICCID or phone number at hand.
Cellular connectivity is dependent on available coverage and good positioning of the device and aerial. If connectivity is not reliable, we recommend repositioning the aerial/device and checking the local area for any network issues flagged up by the mobile operators. Please refer to mobile operator coverage checkers.
