What is SIM900A?
The SIM900A is a readily available GSM/GPRS module,used in many mobile phones and PDA. SIM900A is a dual-band GSM/GPRS engine that works on frequencies EGSM 900MHz and DCS 1800MHz. SIM900A features GPRS multi-slot class 10/ class 8 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
Does SIM900A support 4g?
(900,1800 MHz)it supports only Asian region countries. Considering about the speed you cannot obtain 3g, 4g speed since GSM Shield(SIM900) provides maximum of GPRS class 10: max. 85.6 kbps (downlink) so, It will able to connect but cannot get such speed in 3g and 4g.
What is GSM frequency SIM900?
The SIM900 is a complete Quad-band GSM/GPRS solution in a SMT module which can be embedded in the customer applications. The radio section is GSM phase 2/2+ compatible and is either class 4 (2 W) at 850/ 900 MHz or class 1 (1 W) at 1800/1900 MHz. …
Can we use Jio Sim in SIM900A?
Generally it should work. As SIM900 is just 2g, the 3G sim works in it as 2G. It might be that the sim voltages are not compatible, but it should not be an issue. I have used a 4G sim in a sim 900 module without troubles.
Can we use 4G SIM in sim800l?
Does the SIM800 use a 4G SIM? – Quora. The SIM800 is a GSM/GPRS-only modem module. It can use either a 2G-only SIM or a 3G/4G USIM (which provides compatibility for 2G anyway). It will only work on 2G GSM radio networks so you have to check that in your country – for example it won’t work on the AT or Jio networks.
