Hello ChandanJ,Thanks for your like on this post. Can you tell me which Nextion display you are using?. Basically you can free memory by decreasing the number of text on Page 3 and Page 4. Simply click on each of the buttons and decrease the size. Note this is a repetitive process for each buttons on page 3 and 4.Let me know the outcomes.Best Regards,
Yes you can use the 3.5''. However, I have programmed the 2.4'', and i believe you can still use my source code. However, you need to re-arrange all the items to fit into the 3.5''. Thanks,
Hello Yaswanth,slot for mic and speaker are available in the GSM module.thanks,

Hello Electron_flow, thanks for watching.The sim I used in this project is actually a Nano SIM which supports (LTE, 3G, 2G) and my Mobile Operator is Emtel.Note: The SIM card slot in the GSM module accepts only Normal SIM, as such, I used a "SIM card Multi-Adaptor" to turn the Nano SIM into a Normal SIM, refer to below image.You can select any SIM card from your favorite Mobile Operator available in your region, no matter if it is a prepaid or postpaid, both should actually work.Additionally, you need to confirm with your Mobile Service Provider if they support GSM(2g) network, if you reside in country other than USA then by default its YES.Thanks & Enjoy :-)
Hello Mderton, thank you..
