Any monthly fixed recurring cost if any, for the E1 lines, beside the initial installation.  For the purpose of the evaluation, a scenario based on the current EMSA monthly consumption pattern  increased about 20% will be used, and it is presented under Appendix C. The tenderer is required to develop  its best price plan to minimise the overall cost of the given scenario, using the cost of the bundle proposed  and the cost of calls per minute per destination.  EMSA requires mobile voice and mobile (3G/4G/5G) data communications services in Portugal and abroad in  roaming, and equipment (devices) for mobile communications. SERVICE 2 :  Mobile telephony services and equipment EMSA currently operates about:  These figures are estimated to grow in the coming years. If necessary, the transition phase from the current  operator with number portability shall be organised to avoid any disruption to EMSA operations. Access to  premium rate numbers on these lines can be blocked on EMSA request, as well as it can be possible to set  hard thresholds for data traffic both in Portugal and abroad in roaming to avoid inappropriate usage. Internal  certified antennas could be installed in the EMSA building in order to guarantee a correct use of the mobile  communications.  Tenderers shall provide in  no more than 10 pages  a description of:  •  proposed solution and implementation plan for the transition from the current operator;  •  the customer support services and the service levels.   40 Voice/Data lines (Smartphones);   15 Mobile Internet lines (3G/4G Routers);   16 Tablet Internet lines;   8 only-voice mobile lines.  c)  Monthly fee for packages of minutes of calls toward the main destinations:   Portuguese mobile lines (average of all networks);$^{5}$   Portuguese fixed lines (average of all networks);$^{6}$   EU, USA and Canada fixed lines;$^{7}$   EU, USA and Canada mobile lines.$^{8}$  d) Price per additional minute per destination toward:   Portuguese mobile and fixed lines (all networks);   International phone calls to fixed and mobile lines (separated by country).
