Find new efficiencies with a top SIM provider
As SIM technology and subscribers evolve it is important to have a SIM provider that supports the evolution of your business with secure, interoperable, future-proof solutions. Telcos are also increasingly looking to realise new efficiencies by partnering with a recognised SIM provider who does everything in-house closer to the source, rather than the older traditional SIM providers who rely on multiple, faraway third-party suppliers that severely impact the supply chain time and cost.

Workz new 3 in 1 repluggable SIM card offers mobile users the choice to use their SIM as either a Mini (2FF), Micro (3FF) or Nano (4FF) module. As the module plug-ins are repluggable, meaning they can be taken out of the card and then put back together, users can quickly and easily switch between the three formats as they wish.
Here is a quick guide to remove the SIM plug:
To remove 2FF SIM plug
- Use your forefinger to push out 2FF plug from back (non-chip facing) side
- At the same time use thumb to hold the 2FF plug from the front (chip facing) side
Note: When pushing hold both 3FF and 4FF plug in order to prevent them from breaking up. It is recommended not to try to break out the 2FF plug in one step but rather follow the steps above.
To remove 3FF SIM plug
- Use your forefinger to push out 3FF plug from back (non-chip facing) side
- At the same time use your thumb to hold the 2FF & 3FF plug from the front (chip facing) side To remove 4FF SIM plug
- Use your forefinger to push out 4FF plug from back (non-chip facing) side
- At the same time use your thumb to hold the 2FF & 3FF plug from the front (chip facing) side
To return back the SIM plug
- Place the 2FF/ 3FF/4FF plug back into position from the front (chip facing) side

From French bon à tirer – “good to shoot (print)” BAT card
A BAT card is a non-operational card produced using the materials, inks and finish that will be used in the mass production of the product. Although BAT card cannot be technically tested with a device, both marketing and technical verification is required for printing and personalization details.
BAT approval (graphical profile and physical dimensions)
BAT approval is a document signed by the customer confirming that the product sample (BAT card) has been examined and approved for mass production.
BAT testing can be combined with BAP testing if the BAP card is produced as per the complete graphical and electrical card profile. Both BAT and BAP card approvals play an essential role in the SIM manufacturing process and represent two important elements of T-zero (Time zero is the time when all components are verified and ready for mass production, i.e. purchase order, input data, BAT approval, BAP approval, packing and label requirements).
SIM vendor’s responsibility
It is the SIM vendor’s responsibility to provide a BAT card that is produced as per the ISO standards (ISO/IEC 7816- 1 (1998) – “Physical Characteristics”, ISO/IEC 7816-2 (1999) – “Dimensions and location of the contacts”) and follows agreed customer specifications and confirmed artwork (graphical profile) prior to releasing commercial order for mass production.
During mass production, the SIM vendor is responsible for following the exact specifications, personalization and overall quality as per the approved BAT card. Due to the nature of the printing process, there may be some minor variations in visual appearance within industry tolerances which will not jeopardize the overall integrity of branding or functionality.
The Customer shall notify the vendor of any required changes during digital proofing stage prior to BAT production. It is the customer’s responsibility to examine a BAT card against specifications and artwork and provide written feedback to the Vendor in the form of approval or rejection.
Comparisons to other manufacturer samples are not valid if only introduced after production of BAT and not highlighted at the artwork digital proof stage.
The following characteristics must be checked during BAT approval process. It may not be a comprehensive list of items to review so every element must be checked carefully.
If the BAT card is rejected due to error(s) occurred during BAT production, the Vendor will rectify the issue(s) and provide the second set of BAT cards free of charge.
The vendor shall not accept any responsibility or compensation claims for errors overlooked by the customer and highlighted after BAT approval (refer to the responsibilities section above).
If mass production has not yet commenced such errors can be fixed and a new set of BAT cards provided at additional cost. If mass production has started, the vendor and customer shall mutually agree when and how the issues need to be rectified; all additional costs for such rectification shall be covered by the customer.
- Physical dimensions of card body and measurements: Full, half, quarter size or plug-in only
Form Factor: 2FF, 3FF, 4FF or combination
- Artwork: Match to approved digital proof
- Colour scheme: Match to any defined colours
- Word proofing: Text, language and numbers
- Variable data: Position and syntax of ICCID, IMSI, MSISDN, PIN/PUK, expiry date, etc.
- Barcodes: Presence and position of barcodes
- Finishing: Gloss, matt
- Plug-in area: Quality of cut
BAT testing is not required for repeat production runs (no changes in the graphical profile).
BAT testing can be waived in a case of minor changes on the graphical profile that can be re-proofed via digital proof (position of graphical elements, additional personalization, text, numbers, etc.)
BAT approval form
The customer shall provide a signed BAT approval form supplied along with the physical card sample. No e-mail or verbal approvals will be accepted. Production will commence upon receipt of the signed approval form.
From French bon à produire– “good for production”
A BAP card is a fully operational and personalized card produced with the exact electrical profile with or without artwork (white BAP or full BAP with artwork).
BAP approval (electrical profile, personalization and variable data format)
BAP approval is a document signed by customer confirming that the product sample (BAP card) has been examined, tested and approved for mass production.
BAP testing is a joint responsibility of supplier and customer and includes the following:
- Testing by supplier
- Prior to submission of BAP card to the customer, the supplier shall test the BAP card and verify all elements against the specifications and approved personalization details.
- Supplier shall test BAP cards using common handsets, however, it will not guarantee that all handsets present in a particular market will be covered.
Testing by the customer:
It is the customer’s responsibility to test BAP cards on all handsets sold in their particular market and provide written feedback to the supplier in a form of approval or rejection. In addition, the following tests are the customer’s responsibility:
- Testing of physical SIM characteristics (as per the ISO standards (ISO/IEC 7816-1 (1998) – “Physical Characteristics”, ISO/IEC 7816-2 (1999) – “Dimensions and location of the contacts”)
- Network related configuration
- SIM card security configuration
- Electrical profile configuration
- Handsets compatibility
- Variable data for graphical personalization
If a BAP card is rejected due to any errors found during testing, the supplier will rectify the issues and provide the second set of BAP cards free of charge.
Supplier shall not take any responsibility or accept any compensation claims for errors identified and highlighted after BAP approval. If mass production has not yet commenced such errors can be fixed and a new set of BAP cards provided. If mass production has started, supplier and customer shall mutually agree when and how the issues need to be rectified; all additional costs for such rectification shall be covered by the customer.
BAP testing cannot be waived. A second set of BAP cards can be waived in a case of minor changes on the graphical profile that can be re- proofed via digital proof (position of graphical elements, additional personalization, etc.).]
BAP approval form
Customer shall provide signed BAP approval form supplied along with the physical card sample. No e-mail or verbal approvals will be accepted. Production will commence upon receipt of the signed approval form.
