Cellblok - Mobile Phone Tracking Protection Blocking Bag



Mobile phones can operate on one billionth of the required signal. That is 0.0000000001 of the normal signal strength. Cellblok bags shield to 99.995% at 1GHz. Therefore only 0.005% of the original signal strength remains.
In most instances this level of shielding is sufficient to prevent a call being made or received. However new advances in mobile phone technology may make it possible for an extremely small signal to penetrate the material. This may be sufficient to enable the mobile phone to ring. In over 99% of situations our Cellphone bags provide sufficient blocking.
For this reason we advise that should you not be prepared to accept this eventuality then please do not purchase the product. Returns will not be accepted if your phone falls into this 1% category. Please be advised that this product has been developed to provide shielding for health reason not for security reasons.
