That is problem of low end GSM modules.
- acmdas 5y agoIt's a poor person's problem, doesn't apply here...right?
- ianburrell 5y agoIt is a problem with CDMA that Verizon and Sprint use. CDMA can't do voice and data at the same time. Both Verizon and Sprint have mostly migrated to LTE and VoLTE and are retiring their CDMA networks next year.
