 Not supported by SARA-U270-53S, SARA-U270-73S modules 
5
 Device  can  work  simultaneously  in  Packet  Switch  and  Circuit  Switch  mode:  voice  calls  are  possible  while  the  data  connection  is  active 
without any interruption in service. 
6
 Device  can  be  attached  to  both  GPRS  and  GSM  services  (i.e.  Packet  Switch  and  Circuit  Switch  mode)  using  one  service  at  a  time.  For 
example, if an incoming call occurs during data transmission, the data connection is suspended to allow the voice communication. Once the 
voice call has terminated, the data service is resumed. 
7
 SARA-U260 and  SARA-U270  modules do not  support 8-PSK modulation in uplink; the EDGE Power Class corresponds  to the  GSM/GPRS 
Power Class  
8
 The maximum bit rate of the module depends on the actual network environmental conditions and settings. 
9
 GPRS / EDGE multi-slot class determines the number of timeslots available for upload and download and thus the speed at which data can 
be transmitted and received, with higher classes typically allowing faster data transfer rates. 
10
 GPRS multi-slot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total. 
11
 EDGE multi-slot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total. 
12
 SARA-U260 and SARA-U270 modules support EDGE multi-slot class 12: MCS1-MCS9 up to 236.8 kbit/s DL, MCS1-MCS4 up to 70.4 kbit/s 
UL 
13
 GPRS multi-slot class 10 implies a maximum of 4 slots in DL (reception) and 2 slots in UL (transmission) with 5 slots in total.
