Apply dielectric grease

Note recommends using either the Loctite® LB 8423 Dielectric Grease or Synco Lube® Silicone Dielectric Grease.

1. Use a sheet of paper or cardboard over the area where you intend to work.

2. Use isopropyl alcohol and a cotton-tipped applicator to gently clean the SIM contacts. Using isopropyl alcohol requires a well vented environment. Demineralized water can also be used as an alternative.

   

3. Once the surface is clean and dry, apply a small amount of dielectric grease in a thin layer over the contacts. Use a new cotton-tipped applicator to work the grease smoothy over the contacts. Apply gentle pressure.

4. When the dielectric grease has been applied, insert the SIM into the SIM slot as described above.
