Yes, you can. A quick check of our prohibited items list should highlight that we do accept mobile phone sim cards to be delivered by our courier company partners. Although most of the parcels sent via our parcel delivery network are substantially heavier than a sim card, we do have courier services suitable for such light items, such as DPD, UK Mail, DX and more.
For domestic delivery, you can actually have a sim card collected and delivered the very same day. Many businesses use same day couriers for all kinds of items that can't wait.
Our cheapest UK delivery service is with DPD Pickup, a service where you book online, print the shipping labels and stick them to the box and drop off at any of 2500 + Pickup locations. A courier will then collect your parcel and deliver it in 1-2 working days.
Sim cards are tiny, so we'd suggest that you place your sim card in an envelope and then wrap it up in bubble wrap and sellotape. This then fits comfortably into a mailing bag. You could alternatively use a padded envelope instead. One issue you would need to think about is the value of the sim card and whether you need to add any extended liability
In the UK we are all hooked on our mobile phones and the rest of world is no different so it is no surprise that we see a huge number of sim cards being shipped overseas. Many of these locations are mobile first, with the internet being so widely accessed via phones rather than desktop or laptop. Places such as India are popular delivery destinations for our customers to send sim cards to.
DHL is a very popular courier service to send sim cards with due to their reliability and express shipping times. If you need expedited shipping, DHL is hard to beat.
